In [[proof theory]], a '''sequent''' is a [[Formalism (mathematics)|formalized]] statement of [[Proof theory|provability]] that is frequently used when specifying [[proof calculus|calculi]] for [[deductive reasoning|deduction]]. In the [[sequent calculus]], the name ''sequent'' is used for the construct which can be regarded as a specific kind of [[Judgment (mathematical logic)|judgment]], characteristic to this deduction system.
 
== Explanation ==
A sequent has the form
:<math>\Gamma\vdash\Sigma</math>
 
where both Γ and Σ are [[sequence]]s of [[Mathematical logic|logical]] formulae (i.e., both the number and the order of the occurring formulae matter). The symbol <math>\vdash</math> is usually referred to as ''[[Turnstile (symbol)|turnstile]]'' or ''tee'' and is often read, suggestively, as "yields" or "proves". It is not a symbol in the language, rather it is a symbol in the [[metalanguage]] used to discuss proofs. In a sequent, Γ is called the antecedent and Σ is said to be the succedent of the sequent.
 
== Intuitive meaning ==
The intuitive meaning of the sequent <math>\Gamma\vdash\Sigma</math> is that under the assumption of Γ the conclusion of Σ is provable. Classically, the formulae on the left of the turnstile can be interpreted [[logical conjunction|conjunctively]] while the formulae on the right can be considered as a [[logical disjunction|disjunction]]. This means that, when all formulae in Γ hold, then at least one formula in Σ also has to be true. If the succedent is empty, this is interpreted as falsity, i.e. <math>\Gamma\vdash</math> means that Γ proves falsity and is thus inconsistent. On the other hand an empty antecedent is assumed to be true, i.e., <math>\vdash\Sigma</math> means that Σ follows without any assumptions, i.e., it is always true (as a disjunction).  A sequent of this form, with Γ empty, is known as a [[logical assertion]].
 
Of course, other intuitive explanations are possible, which are classically equivalent.  For example, <math>\Gamma\vdash\Sigma</math> can be read as asserting that it cannot be the case that every formula in Γ is true and every formula in Σ is false (this is related to the double-negation interpretations of classical [[intuitionistic logic]], such as [[Glivenko's theorem]]).
 
In any case, these intuitive readings are only pedagogical. Since formal proofs in proof theory are purely [[syntax|syntactic]], the [[semantics|meaning]] of (the derivation of) a sequent is only given by the properties of the calculus that provides the actual [[rule of inference|rules of inference]].
 
Barring any contradictions in the technically precise definition above we can describe sequents in their introductory logical form. <math>\Gamma</math> represents a set of assumptions that we begin our logical process with, for example "Socrates is a man" and "All men are mortal". The <math>\Sigma</math> represents a logical conclusion that follows under these premises. For example "Socrates is mortal" follows from a reasonable formalization of the above points and we could expect to see it on the <math>\Sigma</math> side of the ''turnstile''. In this sense, <math>\vdash</math> means the process of reasoning, or "therefore" in English.
 
== Example ==
A typical sequent might be: 
 
:<math> \phi,\psi\vdash\alpha,\beta</math>
 
This claims that either <math>\alpha</math> or <math>\beta</math> can be derived from <math>\phi</math> and <math>\psi</math>.
 
== Property ==
Since every formula in the antecedent (the left side) must be true to conclude the truth of at least one formula in the succedent (the right side), adding formulas to either side results in a weaker sequent, while removing them from either side gives a stronger one.
 
== Rules ==
Most proof systems provide ways to deduce one sequent from another. These [[inference rule]]s are written with a list of sequents above and below a [[coplanar|line]]. This rule indicates that if everything above the line is true, so is everything under the line.
 
A typical rule is:
 
:<math> \frac{\Gamma,\alpha\vdash\Sigma\qquad \Gamma\vdash\alpha}{\Gamma\vdash\Sigma}</math>
 
This indicates that if we can deduce that <math>\Gamma,\alpha</math> yields <math>\Sigma</math>, and that <math>\Gamma</math> yields <math>\alpha</math>, then we can also deduce that <math>\Gamma</math> yields  <math>\Sigma</math>.
 
== Variations ==
The general notion of sequent introduced here can be specialized in various ways. A sequent is said to be an '''intuitionistic sequent''' if there is at most one formula in the succedent (although multi-succedent calculi for intuitionistic logic is also possible).  Similarly, one can obtain calculi for [[dual-intuitionistic logic]] (a type of [[paraconsistent logic]]) by requiring that sequents be singular in the antecedent.
 
In many cases, sequents are also assumed to consist of [[multiset]]s or [[Set (mathematics)|sets]] instead of sequences. Thus one disregards the order or even the number of occurrences of the formulae. For classical [[propositional logic]] this does not yield a problem, since the conclusions that one can draw from a collection of premises does not depend on these data. In [[substructural logic]], however, this may become quite important.
 
== History ==
Historically, sequents have been introduced by [[Gerhard Gentzen]] in order to specify his famous [[sequent calculus]]. In his German publication he used the word "Sequenz". However, in English, the word "[[sequence]]" is already used as a translation to the German "Folge" and appears quite frequently in mathematics. The term "sequent" then has been created in search for an alternative translation of the German expression.

If you are reading this article then I can securely assume you are searching for certain hemorrhoid treatments you are able to do at house. If you are, then please read on. Let you initially define what hemorrhoids are plus what causes them, following understanding which, then you can find effective home treatments you may use. Basically hemorrhoids are swollen veins inside our anal canal. It is synonymous to varicose veins, nevertheless instead of it being inside the legs it really is found inside our anal canal.

There are 2 problems associated with utilizing creams. The initially is that several individuals experience burning sensations, occasionally thus bad which we must discontinue the use of the cream. The second problem is the fact that lotions never treat the underlying problems that cause hemorrhoids; consequently lotions are a temporary thrombosed external hemorrhoid treatment.

H-Miracle by Holly Hayden is not a cream or topical answer however, a step-by-step guide to get rid of hemorrhoids. It offers a holistic approach to treating hemorrhoids: what to consume, what to not eat, what to do plus what not to do. It also comes with a great deal of freebies like books on "How to Ease Your Allergies" and "Lessons from Miracle Doctors". A great deal of customers like it due to the effortless to follow instructions and the capability of the all-natural solutions utilized. Plus they additionally provide a funds back guarantee only in case the system doesn't work for you or anyone inside the family that is experiencing hemorrhoids.

It is true which all these aspects cannot be covered by modern conventional medications because they tend to work found on the symptoms alone and not found on the cause of hemorrhoids. Hemorrhoids are caused due to different underlying wellness conditions which include the digestive system, the belly, the bowel movements, the diet, our life-style and also our sleeping patterns. With conventional medicine, it is merely impossible to take care of all these aspects.

Your health food shop has a wealth of herbal hemorrhoid treatments, all of that contain secure elements and are effortless on the purse. Barberry, Butcher's Brew, Witch Hazel, Horse Chestnut plus Slippery Elm are all famous herbal elements for giving relief whenever piles flare up.

Only sit for threee to five minute for a bowe movement plus don't wait till the last minute as sometimes the body tend to have a temporary or false irregularity plus by the time you need to, nothing comes out (I understand, I have performed this before).

Although these seven steps are all great ways to heal hemorrhoids, they are no promise that you will be capable to completely heal a hemorrhoids or which they won't return. As a guideline, when symptoms do not clear up completely, come back in a few days or deteriorate at some point in drugs, you need to receive an appointment to pay a visit to your general practitioner appropriate away.
