RESULT ON VARIATIONAL INEQUALITY PROBLEM 1
... Consider G : T (A) → A defined by G(y) = {z ∈ A : f (z, y) ≤ f (w, y) for all w ∈ A}. For each y ∈ T (A), G(y) is nonempty since f assumes its minimum on the compact set A. Also, it is closed and hence compact. Further, G(y) is acyclic. Indeed, let z1 and z2 ∈ A be such that f (zi , y) ≤ f (w, y) fo ...

... and the whole space X are the only subsets of X that are both open and closed. Lemma 3.1 A topological space X is connected if and only if it has the following property: if U and V are non-empty open sets in X such that X = U ∪ V , then U ∩ V is non-empty, Proof If U is a subset of X that is both op ...

... Generally, for 0 < p ≤ ∞, define the Hardy space H p = H p (Rn ) = {u ∈ S ∗ : for some ϕ ∈ S, Mϕ u ∈ Lp } The Hardy spaces H p , with 0 < p ≤ 1 in some sense replace the Lp spaces for p < 1. The analogous definitions for p > 1 provably give Lp = H p , while this is not at all so for p ≤ 1. For p = 1 ...
