A publication of the Theta Foundation

The volume is a careful selection of peer-reviewed papers in operator
theory, structured matrices, and dilations, dedicated to Tiberiu
Constantinescu, a prominent mathematician in the field.

The extensive survey of J. W. Helton and M. Putinar on positive polynomials,
spectral theorem, and optimization is a pioneering essay that, under the
unifying concept of positivity, brings together ideas from algebra, algebraic
geometry, complex analysis, control theory, mathematical logic, and operator
theory.

The other research papers deal with recent advances in the
following areas:

- multivariable operator theory
- interpolation and moment problems
- perturbation theory
- composition operators
- matrix completion problems
- systems theory

A publication of the Theta Foundation. Distributed worldwide, except in Romania, by the AMS.
