LINEAR ALGEBRA AND ITS APPLICATIONS Special Issue in honor of Paul Fuhrmann Second Announcement with extended submission deadline Linear Algebra and its Applications is pleased to announce a special issue in honor of Professor Paul Fuhrmann on the occasion of his 70th birthday on 5 August 2007 in recognition of his many important and fundamental contributions to linear algebra and control theory. We solicit papers for the special issue within the entire scope of LAA or the research interests of Paul Fuhrmann. We welcome papers within system and control theory and operator theory; in particular in * algebraic systems theory * approximation, identification and interpolation * behavioral theory * coding theory with relations to systems theory * functional models * geometric control * hybrid and discrete event systems * matrix-valued and operator-valued functions * model reduction * multidimensional systems * numerical and computational aspects * operators, systems, and linear algebra * polynomial methods in systems theory * robust and optimal control * spectral factorizations * stability theory * system structure * uncertain systems * Wiener-Hopf factorizations The deadline for submission of papers is 31 July 2006. Papers for submission should be sent to any of the five special editors, preferably pdf files as attachments in email, and will be subject to normal refereeing procedures according to LAA standards: Athanasios C.
