5. Algebraic and
analytic aspects of Hilbert space operators |

M. Ptak Krakow, Poland rmptak@cyf-kr.edu.pl |

On the other hand, the presence of analytic structure within the space provides more tools extends substantially the scope. The proposed subject includes both means separately as well as a join of them.

Among traditional examples of the latter one finds shift operators of any kind, Toeplitz and Hankel operators or composition ones, as to mention some possibilities. The list of examples can be extended much beyond this. Needless to say that unbounded operators fit well into this scheme, and this allows to take advantage of rich source of applications in Classical and Quantum Mechanics extending those already located in Pure and Applied Mathematics.

Theory, Real Algebraic Geometry, And Moment Problems |

We are dedicating this session to the memory of Murray Marshall (24.3.1940--1.5.2015), one of the foremost specialists on positive polynomials and moment problems. He will be sorely missed | ||

Moment problems have been both at the
heart and at the crossroads of numerous disciplines in pure and
applied mathematics since their first appearance in the work of
Stieltjes more than a century ago. They certainly occupy a
prominent position in the field of operator theory and its
applications. While Havilandâ€™s Theorem (1935) related the
solvability of a multidimensional moment problem to positive
polynomials, it was only in the last two decades that moment
problems came to play an important role in the field of real
algebraic geometry, that grew largely out of Hilbertâ€™s 17th
problem on representing a positive real rational function as a
sum of squares of real rational functions. The purpose of this
thematic session is to bring together specialists in these two
fields, both those that are traditional

8. Free
Noncommutative Analysis And Its Applications |
||

Organizers |
||

J.A. Ball Virginia Tech, USA, joball@math.vt.edu |
V. Vinnikov Ben Gurion University of the Negev, Israel vinnikov@math.bgu.ac.il |

Functions of free noncommuting
variables were first considered by Joseph L. Taylor in his
monumental work on noncommutative spectral theory in the 1970s.
They became a topic of active research in the last several
years, as a fertile ground for considering the analogues of many
problems of classical analysis in several complex variables and
related problems in multivariable operator theory,

and as an important tool in free probability and free
noncommutative algebraic and semialgebraic geometry and
convexity.

The purpose of this thematic session is to give a venue for
presenting some recent results in this rapidly developing area
of operator theory and its applications.
