Objectives of the Course

The purpose of this course is to explain the dual spaces of the Banach and Hilbert spaces, their properties, and the basic concepts of the linear transformations (operators, functionals) theory defined in these spaces, and their applications. For example, Lebesgue, Sobolev et al. space and differential, integral and other linear transformations.The students can understand the works about these themes.

Name of Lecturer(s)

Prof. Dr. Kamal SOLTANOV

Learning Outcomes

1	To explain to students why Banach and Hilbert spaces, their properties and their properties are important
