Possible reasons for this negligence might be that multiplication of distributions is not defined in general [44], and that spaces of distributions tend to be locally convex while the focus was on fractional powers of operators on normed spaces [27, 45,46,47,48]. Later, in [27], ...

Since linear mappings defined on finite dimensional normed spaces are always bounded, also C[z1, . . . , zn]≤d s → sM ∈ F is bounded. Thus, we verified the first part of the present assertion. For given φ∈ F and s ∈ C[z1, . . . , zn] as in Lemma 5.10 the ...

Suppose that f(x) is continuous on [a, b] and differentiable at (a, b), and that F(x) is the antiderivative of f(x). Then, we have the following:Let's rewrite the preceding equation a bit so it becomes this equation:All we have done here is replace x with t and b with x....
One key ingredient in the proofs is a version of the Acerbi-Fusco estimate (1.2) for simplices rather than pairs of points in Lemma3.1. For the estimate, let us considerwithand letDbe a simplex with verticesand a normal vector
Calculus on normed vector spacesLarson, D SChoice
The inverse of a one-to-one continuous linear mapping of one normed vector space onto another need not be continuous. The partial differentials of a differentiable mapping are defined on the product of two normed vector spacesandThe finite-dimensional implicit mapping theorem follows from the ...
In particular, ever greater attention is being paid to the study of functionals J(x) of a very general type, definable on sets Gx of elements of normed spaces. For problems of this kind, it is difficult to use the method of variations. New methods have been developed based on the use ...
