LINEAR ALGEBRA AND ITS APPLICATIONS
                Special Issue in honor of Heydar Radjavi


        Linear Algebra and its Applications is pleased to announce a
special issue in honor of Professor Heydar Radjavi, in recognition of his
many important contributions to linear algebra and to operator theory,
and in celebration of his 70th birthday on January 17, 2005.
        Heydar's early results include his seminal characterization of
self-commutators of operators on Hilbert space.  His definitive trace
condition for simultaneous triangularizability of semigroups of matrices
was the culmination of work on this topic by several generations of
distinguished algebraists.  Heydar has obtained numerous other results of
broad interest on invariant subspaces, simultaneous triangularizability,
products of involutions, semigroups of matrices and many other topics. As
he approaches 70, his research productivity is increasing with his age.
It is hoped that this special issue will reflect the breadth and
influence of his research.
        Papers on any aspect of linear algebra or operator theory may be
submitted to any of the four special editors listed below before July 31,
2003. Submissions will be subject to the normal refereeing procedures and
standards of LAA.
