Given a point xo EX and a real number r>0, we define three types of sets: (a) B(xo; r) {xe X d(x, xo)0 there is a 8>0 such that (see Fig. 6) d(Tx, Txo)< for all x satisfying d(x, xo)<8. T is said to be continuous if it is continuous at every point of X. ■ 1.3-4 Theorem (Continuous mapping). A mapping T of a metric space X into a metric space Y is continuous if and only if the inverse image of any open subset of Y is an open subset of X.

Problem 1: Spectral Theorem for Compact Self-Adjoint Operators on Hilbert Spaces Statement: Let H be an infinite-dimensional separable Hilbert space over C, and let T: H→ H tea compact, self-adjoint operator. Tasks: 1. Eigenvalue Sequence Construction •Prove that the non-zero spectrum of T consists of a sequence {A} C IR converging to zero. Show that each A, has finite multiplicity. 2.
