Abstract

Operators defined in infinite-dimensional spaces (Banach and Hilbert) and spectral theory on Hermitian operators will be studied. To do this, we will see some results on continuous n-linear applications, the adjoint and the unitary, normal and Hermitian operators. We will apply this theory to the Fredholm Alternative. Furthermore, using the theory of compact Hermitian linear operators, we want to introduce the Sturm-Liouville Problem, which consists of solving a differential system. Finally, we will study the optimization of functions defined in infinite-dimensional spaces. Here we will need the definition of the derivative for this type of function, we will address the Fréchet and Gâteaux derivatives.
