WebDefinitions. A topological homomorphism or simply homomorphism (if no confusion will arise) is a continuous linear map: between topological vector spaces (TVSs) such that the induced map : is an open mapping when := (), which is the image of , is given the subspace topology induced by . This concept is of considerable importance in functional analysis … WebEvery uniformly convex space is strictly convex. Intuitively, the strict convexity means a stronger triangle inequality‖x+y‖<‖x‖+‖y‖{\displaystyle \ x+y\ <\ x\ +\ y\ }whenever x,y{\displaystyle x,y}are linearly independent, while the uniform convexity requires this inequality to be true uniformly. Examples[edit]
