The fourth axiom in the definition of real random normed module is superfluous. A necessary and sufficient condition is given that continuous random linear functionals over complex random normed spaces are a.s. bounde...
Let X be a normed linear space and A a subspace of X. The n-widths of A, relative to X in the sense of Kolmogorov, is given by, where the X_n range over all subspaces of X of dimension at most n. The Kolmogorov n-widt...
Ⅰ. PROBLEM AND ASSUMPTIONS In 1978 J. Henry first discussed the globe controllability problem on a semilinear parabolic system with a distributed control. The author obtained the approximate control lability theory o...
The concept of probabilistic metric spaces was introduced by Menger in 1942.Based on the similar idea, the concept of random normed spaces (i. e. probabilistie linear normed spaces) was presented by Serstnev.Since the...
Let X be normed linear space, 8 (X)={x∈X|‖x‖ = 1}. The author tried to introduce the concept of the function of convexity for any BANACH space, as J. A. Clarkson had introduced the concept of modulus of convexity f...
