2009 CANADIAN MATHEMATICAL SOCIETY G. DE B. ROBINSON AWARD WINNERS
The Canadian Mathematical Society is pleased to announce that
Dr. Vladimir Manuilov (Moscow State University) and Dr. Klaus Thomsen (Aarhus
University) are the winners of the 2009 G. de B. Robinson Award.
The G. de B. Robinson Award was inaugurated to recognize the publication of
excellent papers in the Canadian Journal of Mathematics and the Canadian
Mathematical Bulletin and to encourage the submission of the highest quality
papers to these journals.
The 2009 G. de B. Robinson Prize is awarded to V. Manuilov and K. Thomsen for
their paper "On the Lack of Inverses to C*--extensions related to property T
groups" (Canadian Mathematical Bulletin 50 (2007), no. 2, 268-283).
The Connes-Higson construction [A. Connes and N. Higson, C. R. Acad. Sci. Paris
Sér. I Math. 311 (1990), no. 2, 101--106] is one of the most fundamental
constructions of E-theory. In E-theory, utilizing the notion of asymptotic
morphism, an extension is viewed as trivial when it is asymptotically split,
and as semi-invertible when its direct sum with some other extension is
trivial. In earlier work [J. Funct. Anal. 213 (2004), no. 1, 154--175], V.
Manuilov and K. Thomsen show that when dealing with a suspension, every
extension is semi-invertible.
The authors are able to modify an example investigated by S. Wassermann [Ann.
of Math. (2) 134 (1991), no. 2, 423--431] to get an extension which is not
invertible up to homotopy. This paper then provides the first example of a
C*--algebra for which the semigroup of homotopy classes of extensions is not a
group.
Professor Vladimir Manuilov was born in Kishinev, USSR, in 1961 and obtained
his Diploma in Mathematics in 1983 and his Ph.D. degree from Moscow State
University in 1987, under the supervision of Alexander Mishchenko. He obtained
a second higher doctoral degree in 2000, also from Moscow State University. He
began teaching at the same university in 1995 and became a full professor in
2003. Vladimir Manuilov has lectured and worked in several other universities,
particularly at the Harbin Institute of Technology (China). Two graduate
students have obtained their Ph.D. degrees under Manuilov's supervision. He is
also the author of 50 publications, including a monograph, with E. Troitsky,
entitled "Hilbert C*--modules" which was published by the AMS in 2005. His main
area of research has been on K-theory of C*--algebras. His collaboration with
Klaus Thomsen on asymptotic homomorphisms and extensions of C*-algebras started
in 1998 and has resulted in a series of 13 joint papers.
Klaus Thomsen received his Ph.D. from the University of Aarhus in 1985 and has
been an Associate Professor since 1988. His main interests are in operator
algebras and dynamical systems, and, in particular, the interplay between these
two areas. On a more personal level he is married and the proud father of two
sons and a daughter.
