In mathematics, a Weierstrass ring , named by harvtxt Nagata 1962 loc section 45 after KarlWeierstrass , is a commutative ring commutative local ring that is Henselian , pseudo geometric , and such that any quotient ring by a prime ideal is a finite extension of a regular local ring . Examples The Weierstrass preparation theorem can be used to show that the ring of convergent power series over the complex numbers in a finite number of variables is a Wierestrass ring. The same is true if the complex numbers are replaced by a perfect field with a valuation. Every ring that is a finite module over a Weierstrass ring is also a Weierstrass ring.

It also lies very near the crater Van Vleck crater Van Vleck , a similar formation just to the southeast that is almost attached to the outer rim. Due to its location, the crater appears foreshortened as seen from the Earth . The crater has an oval shaped outer rim that is longer along an east west axis. There are some slumped shelves along the inner walls to the north and south. The interior floor is nearly featureless, with only a few tiny impacts. Neither the rim nor the interior are marked by impact craters of significance. Prior to being named by the International Astronomical Union IAU , this crater was designated Gilbert N.

Formal statement of the theorem Start with some open set open subset U in the complex number complex plane containing the number z sub 0 sub , and a function f that is holomorphic function holomorphic on U     z sub 0 sub , but has an essential singularity at z sub 0 sub   . The Casorati Weierstrass theorem then states that if V is any Neighbourhood mathematics neighbourhood of z sub 0 sub contained in U , then f V     z sub 0 sub is dense set dense in C . This can also be stated as follows for any &epsilon 0, &delta 0, and complex number w , there exists a complex number z in U with z &minus z sub 0 sub &delta and f z &minus w &epsilon   . Or in still more descriptive terms f comes arbitrarily close to any complex value in every neighbourhood of z sub 0 sub . This form of the theorem also applies if f is only meromorphic . The theorem is considerably strengthened by Picard s great theorem , which states, in the notation above, that f assumes every complex value, with one possible exception, infinitely often ...

In mathematics , the Weierstrass preparation theorem is a tool for dealing with analytic function s of several complex variables , at a given point P. It states that such a function is, up to multiplication by a function not zero at P, a polynomial in one fixed variable z , which is monic polynomial monic , and whose coefficient s are analytic functions in the remaining variables and zero at P. There are also a number of variants of the theorem, that extend the idea of factorization in some ring mathematics ring R as u w , where u is a Unit ring theory unit and w is some sort of distinguished Weierstrass polynomial .

Wikify date February 2011 Unreferenced date March 2009 The Weierstrass&ndash Erdmann condition is a technical tool from the calculus of variations . This condition gives the sufficient conditions for an extremal to have a corner. Conditions The condition says that, along a piecewise smooth extremal x t i.e. an extremal which is smooth except at a finite number of corners for an integral math J int f t,x,y ,dt math , the partial derivative math partial f partial x math must be continuous at a corner  T . That is, if one takes the limit of partials on both sides of the corner as one approaches the corner  T , the result must be the same answer. Applications The condition allows one to prove that a corner exists along a given extremal. As a result, there are many applications to differential geometry. In calculations of the Weierstrass E Function, it is often helpful to find where corners exist along the curves. Similarly, the condition allows for one to find a minimizing curve for a given integral. DEFAULTSORT Weierstrass Erdmann Condition Category Calculus of variations ... more details
In mathematics , the Weierstrass M test is a criterion for determining whether an infinite series of function mathematics functions converges uniform convergence uniformly . It applies to series whose terms are functions with real number real or complex number complex values, and is analogous to the comparison test for determining the convergence of series of real or complex numbers. Statement Suppose that math f n math is a sequence of real or complex valued functions defined on a Set mathematics set math A math , and that there is a sequence of positive numbers math M n math satisfying math f n x leq M n math for all math n geq 1 math and all math x in A math . Suppose also that the series math sum n 1 infty M n math is convergent. Then the series math sum n 1 infty f n x math converges uniform convergence uniformly on math A math . Remark The result is often used in combination with the uniform limit theorem . Together they say that if, in addition to the above conditions, the set math A math is a topological space and the functions math f n math are continuous on math A math , then the series converges to a continuous function. Generalization A more general version of the Weierstrass M test holds if the codomain of the functions math f n math is any Banach space , in which case the statement math f n leq M n math may be replaced by math f n leq M n math , where math cdot math is the norm on the Banach space. For an example of the use of this test on a Banach space, see the article Fr chet derivative . Proof Suppose that the conditions stated above hold.
