Aims
To present some results from the duality theory for locally convex spaces and from Banach space theory, which are most used in optimization and best approximation problems.
Content
Support functionals - Bishop-Phelps subreflexivity and James reflexivity theorems. Geometric properties of normed spaces -strict convexity, local uniform convexity and uniform convexity. Extremal points and support functionals of the unit balls in concrete Banach spaces. Differential and integral calculus in Banach spaces. Convex functions - continuity and differentiability. Smoothness properties of normed spaces - Gateaux and Frechet differentiability of the norm. Holomorphic vector functions - the equivalence of weak and strong holomorphy.
