Given a Polish space X, I note $C_b(X)$ the set of the continuous bounded functions with the norm of the uniform convergence, and and $(C_b(X))^\star$ its topological dual with the $*-$weak ...
Normally measures and probability spaces are defined over $\sigma$-algebras. I was wondering what would happen if one tries to define it over frames in place of $\sigma$-algebras? (i.e. complements do ...
Suppose X' and Y are Banach spaces and X is a linear subspace dense in X'. Let T be a continuous map of X to Y satisfying: (1) ||T(x+y)|| is less than or equal to ||T(x)||+||T(y)||. Please prove ...
