22. Fredholm Alternative for Compact Operators
Let T: XX be a compact operator on a Banach space X. Prove the Fredholm Alternative:
either T - AI is invertible for all A0, or there exists a nonzero AE(T) such that A is an
eigenvalue of T. Show how this result applies to integral operators on I² ([a, b]).
Hint: Consider the structure of the spectrum of compact operators and the implications of non-
invertibility.
23. Hölder's Inequality and Duality in
Spaces
Let 1 <p< ∞ and let q be the conjugate exponent defined by += 1. Prove Hölder's
inequality and use it to establish that every fЄ LP (2) defines a bounded linear functional on
L() by of(g) = fg du. Show that this mapping gives an isometric isomorphism between LP
and the dual of L" for 1 <p<0.
⚫Hint: Use the Minkowski and Hölder inequalities for the duality result.
