Mathematics of Computation, Vol. 25, No. 115 (Jul., 1971), pp. 413-424 (12 pages) The weak sequential compactness of reflexive Banach spaces is used to explain the fact that certain ill-posed, linear ...

Infinite-dimensional systems, characterised by state spaces of infinite dimension such as those described by partial differential equations, present profound challenges and opportunities within ...

Let (G,X) be a locally compact transformation group. We characterize when the associated transformation-group C*-algebra C0(X) ⋊ G has bounded trace. If G acts freely on X, then C0(X) ⋊ G has bounded ...
