Book DetailsTheta Foundation International Book Series of Mathematical TextsVolume: 10; 2007; 356 ppMSC: Primary 00; Secondary 47;
The volume is a careful selection of peerreviewed 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
ReadershipGraduate students and research mathematicians interested in analysis.
