We use the symbol :=, for example, f(x)= r² to say that the function f is defined by setting f(x) = r² for all in the domain. This is same as writing f(x) 2. Can you guess what the symbol a² f(a) means? LIIS RIIS means that RIIS is defined by LIIS. dof I started with the principle that a first course in functional analysis is meant first as a part of the general culture and second as an important tool for any future analyst. llence the emphasis all through had been to look at concrete spaces of function and linear maps between them. This has two advantages: (1) the students get to see the typical applications of the results of functional analysis to other parts of analysis and (2) while dealing with such 9. Sobolev Spaces and Embedding Theorems Let CR" be a bounded open subset with a smooth boundary. For 1 , then WP (2) is continuously embedded in C(S), the space of continuous functions on 2. • Hint: Use the Sobolev embedding theorem and analyze how the choice of k and p affects continuity. 10. Closed Graph Theorem and Applications Let X and Y be Banach spaces, and let T: XY be a linear operator. Prove the Closed Graph Theorem, which states that if I has a closed graph (ie., if x, x in X and T(x) → y in Y imply T(x) = y), then I is continuous. Then, apply this result to show that if I is a densely defined linear operator on L²(R) with a closed graph, then I is bounded. Hint: Argue by considering sequences in X and show that the graph being closed implies the continuity of T.
