### Organizers

Dr Zinaida Lykova, Dr Michael Dritschel, Dr Evgenios Kakariadis, Dr David Kimsey.

### Objective

Our topic will be a powerful machinery that has been developed in the last 60 years both to
discover and to prove theorems about analytic functions in one and several complex variables
through the construction of operators on Hilbert space.

The lectures will begin with expositions of the elementary operator theory that is required
to achieve interesting results in function theory.

Next we will show how a number of classical results in the theory of analytic functions in one variable,
when cast in a Hilbert space setting, can be proved by operator-theoretic methods
which are largely algebraic in nature.
These results will include the Herglotz Representation Theorem,
the Caratheodory and Pick Interpolation Theorems,
Nevanlinna's Representation Theorems, the Caratheodory-Julia Theorems, and Loewner's Theorem.

The remainder of the talks will focus on how the operator-theoretic proofs of these one-
variable theorems can be generalized to yield a variety of new results in several complex variables.

The annual Invited Lecturers scheme aims to bring a distinguished overseas mathematician to
the United Kingdom to present a small course of about ten lectures spread over a week. Each
course of Invited Lectures is on a major field of current mathematical research, and is instructional
in nature, being directed both at graduate students beginning research and at established
mathematicians who wish to learn about a field outside their own research specialism.
