Problem 24: Compactness in Function Spaces
Problem Statement:
Compactness in function spaces often requires specific conditions beyond boundedness.
Tasks:
a) Rellich-Kondrachov Theorem: State the Rellich-Kondrachov Compactness Theorem for Sobolev
spaces.
b) Application to Partial Differential Equations: Explain how the Rellich-Kondrachov Theorem is
used in proving existence results for solutions to elliptic PDEs.
c) Compact Embedding of Sobolev Spaces: Prove that Wk(2) embeds compactly into L" (S2)
under appropriate conditions on k, p, and q.
d) Visualization: For ? = (0, 1) and W12 (2), illustrate the embedding into L² (?) by showing
how bounded sequences have convergent subsequences in L². Include graphs of example functions
and their limits.
where p > 1.
