The analysis might study the spectrum of an individual operator or the semigroup structure of a collection of them.

NSF Focused Research Group: Wavelets, Frames, and Operator Theory This FRG will enhance collaboration among the members by: holding regular think-tank-style workshops, involving students and postdocs in those workshops, exchanging students for short visits among the Principal Investigators, forming project subgroups to attack specific problem areas. Contents A sample of the FRG research problems Project areas Participants Events ... Reports A sample of the FRG research problems: Definition: A subset is said to be a wavelet set for an expansive integral matrix if the inverse Fourier transform of is a wavelet, i.e., if the double indexed family , is an orthonormal basis for . (This is equivalent to tiling both under the translations and the scalings Problem A: Wavelet set implementation. Because of the structure of wavelet sets, their explicit constructions, and the potential usefulness of dealing with only one wavelet in higher dimensions, there are two immediate and natural problems. We wish to develop recursive programmable schemes for applications, cf. [BT93, Stro00a, Wic94], as well as a theoretical formulation in terms of frames, cf. [HL00, Han97]. This latter approach would sacrifice orthonormality, which is often not a sacrifice in applications dealing with noise reduction and stable representation. On the other hand, the frame theoretic approach would reduce the recursive complexity, it would add smoothness in the spectral domain, and it would provide an iterative method of signal reconstruction. Related to this whole issue is the necessity of a critical comparison of the geometrical constructions in [BS01] and the theoretical but constructive approach in [BMM99] in terms of multiplicity functions and finite von Neumann algebras.

Introduction Participants include not only U.S. and Canadian mathematicians, but also some from Europe, Japan and Australia. The conference is not focused on a single theme, but encompasses a wide spectrum of operator theory and operator algebras, including applications. Thus, we have invited plenary speakers working in Von Neumann algebras, classification of C -algebras, nonsefladjoint algebras (including groupoid theory, inductive limit algebras), applications to statistics and electrical engineering. GPOTS is an opportunity for graduate students who are nearing completion and for young postdocs to talk about their work, and to meet with and interact with more established researchers. 2.

30. History Of Operator Theory In the first textbook on operator theory, Théorie des Opérations Linéaires, published in Warsaw 1932, Stefan Banach states that the subject of the book is http://www.mathphysics.com/opthy/OpHistory.html

A Short History of Operator Theory by Evans M. Harrell II In the first textbook on operator theory, published in Warsaw 1932, Stefan Banach states that the subject of the book is the study of functions on spaces of infinite dimension, especially those he coyly refers to as spaces of type B, otherwise Banach spaces definition This was a good description for Banach, but tastes vary. I propose rather the "operational" definition that operators act like matrices . And what that means depends on who you are. If you are an engineering student, matrices are particular symbols you manipulate to solve linear systems. As a working engineer you may instead use Heaviside's operational calculus, in which you are permitted to do all sorts of dangerous manipulations of symbols for derivatives and what not, exactly as if they were matrices, in order to solve linear problems of applied analysis. About 90% of the time you will get the right answer, just like the student; somewhat more with experience. And that is good enough, if the bridges you build aren't where I drive. In mathematics the student of elementary analysis learns that matrices are linear functions relating finite-dimensional vector spaces, and conversely. As a working mathematician the analyst has lost all fear of minor matters like infinity, and will happy agree with Banach's definition.

31. IWOTA 2004 International Workshop on Operator Theory and Applications. University of Newcastle, UK; 1216 July 2004. http://www.ncl.ac.uk/iwota/

Newcastle upon Tyne 12-16 July 2004 The next International Workshop on Operator Theory and Applications (IWOTA) is being organised at the University of Newcastle, Newcastle upon Tyne, UK, where it will be held from Monday, 12 July to Friday, 16 July, 2004. IWOTA is conveniently scheduled near the time of the MTNS meeting (Mathematical Theory of Networks and Systems), to which it started off as a satellite conference. In 2004, MTNS will be held the preceding week in Leuven, Belgium. This IWOTA meeting will be the fifteenth in a series of highly successful IWOTA meetings. The previous IWOTA meetings were held in Santa Monica (1981), Rehovot (1983), Amsterdam (1985), Mesa AZ (1987), Rotterdam (1989), Sapporo (1991), Vienna (1993), Regensburg (1995), Bloomington (1995), Groningen (1998), Bordeaux (2000), Faro (2000), Blacksburg (2002) and Cagliari (2003). The organisers of the present meeting intend to adhere to the high standards set by these previous meetings. The purpose of IWOTA 2004 is to bring together mathematicians and engineers interested in operator theory and its applications. Adhering to to the tradition of recent meetings, our focus is primarily on a few special themes, suggested by research existing at Newcastle University and other British universities:
