The '''Radon–Riesz property''' is a mathematical property for [[normed space]]s that helps ensure [[limit of a sequence|convergence]] in norm. Given two assumptions (essentially weak convergence and continuity of norm), we would like to ensure convergence in the [[norm topology]].


==Definition==
Suppose that (''X'', ||·||) is a normed space. We say that ''X'' has the ''Radon–Riesz property'' (or that ''X'' is a ''Radon–Riesz space'') if whenever <math>(x_{n})</math> is a sequence in the space and <math>x</math> is a member of ''X'' such that <math>(x_{n})</math> [[weak topology|converges weakly]] to <math>x</math> and <math>\lim_{n\to\infty} \Vert x_n \Vert = \Vert x\Vert </math>, then <math>(x_{n})</math> converges to <math>x</math> in norm; that is, <math>\lim_{n\to\infty} \Vert x_n - x\Vert = 0 </math>.

Although it would appear that [[Johann Radon]] was one of the first to make significant use of this property in 1913, [[Mikhail Kadets|M. I. Kadets]] and V. L. Klee also used versions of the Radon–Riesz property to make advancements in [[Banach space]] theory in the late 1920s. It is common for the Radon–Riesz property to also be referred to as the '''Kadets–Klee property''' or '''property (H)'''. According to Robert Megginson, the letter H does not stand for anything. It was simply referred to as property (H) in a list of properties for normed spaces that starts with (A) and ends with (H). This list was given by K. Fan and I. Glicksberg. The "Riesz" part of the name refers to [[Frigyes Riesz]]. He also made some use of this property in the 1920s.
 
==Example==
Every real Hilbert space is a Radon–Riesz space. Indeed, suppose that ''H'' is a real [[Hilbert space]] and that <math> (x_{n}) </math> is a sequence in ''H'' converging weakly to a member <math> x </math> of ''H''. Using the two assumptions on the sequence and the fact that
:<math>\langle x_{n} - x, x_{n} - x\rangle = \langle x_{n} , x_{n} \rangle - \langle x_{n} , x\rangle  - \langle  x, x_{n} \rangle + \langle  x, x\rangle, </math>
and letting ''n'' tend to infinity, we see that
:<math>\lim_{n\to\infty}{\langle x_{n} - x, x_{n} - x\rangle} = 0. </math>
Thus ''H'' is a Radon–Riesz space.

The past five years, owners of California real estate have already been hitting the ball out of the appreciation ballpark. Yes, a housing market on steroids.

California

California is heavily used from north to south across the coastline, nevertheless they express offers somewhat different ecologies. In Northern California, one is much more likely to see symptoms of the four months, get winter and more old sense in locations such as Bay Area. Southern California, on the other hand, has an extremely moderate climate with temperatures rarely sinking below 60 degrees even in the wintertime. To get extra information, we know you check out: http://www.funnyordie.com/sellthatcar. Rainfall can be scant with San Diego getting around 11 inches a-year. In the event that you are considering moving to California, there are two constants throughout the state.

Traffic

So many people have moved to the state that traffic could be a real problem even o-n weekends. Los Angles traffic is popular, but San Diego and San Francisco have their own congestion dilemmas.

Earthquakes

Earthquakes really are a constant throughout the state as the San Andres Fault bisects a lot of the state. Buy Http://Sellthatcar.Livejournal.Com/Profile includes more about the meaning behind it. Earthquakes happen all of the time, however they are generally very small. If you live in California for a lot more than monthly, you will not even notice them. We discovered visit link by browsing newspapers.

Shores, Culture and Sun

There are serious benefits to residing in California. Foremost, of course, are the beaches. This is the position, if the thought of spending weekends and evenings on the beach that suits you. Youll pay reduced for it, but there"s nothing like it. For example, the temperature in San Diego o-n October 5, 2005, the day I"m writing this, is 7-9 degrees!

Florida Property

California can be an incredible place to live and real estate prices reflect it. Single-family house prices average the following for the three major towns - $620,000 for San Diego, $1,300,000 for central San Francisco and $750,000 for central La. As a broad rule, the closer the house is to the water, the more it will cost.

As surprising as the rates are, the rate of appreciation is utterly impossible-to believe. Within the last 12-months, California real estate has appreciated over 25 percent. For-a 500,000 home, that"s a of $125,000 in 12-months. Steroids indeed!

Property is focused on location, location, location. While this is actually a clich, there is no doubt it"s true in California..
