Optimization & Numerical Analysis seminars. A framework for structured linearizations of matrix polynomials in various bases. – Raf Vandebril – KU Leuven (Il Seminario si svolgerà nella Sala Seminari Ovest, Dipartimento Informatica, Università di Pisa.)

We present a framework for the construction of linearizations for scalar and matrix polynomials based on dual bases which, in the case of orthogonal polynomials, can be described by the associated recurrence relations. The framework provides an…

Optimization & Numerical Analysis seminars. Minimization algorithms for compressive sensing. – Andrea Masciotta – Dipartimento di Matematica Università di Pisa (Il Seminario si svolgerà nella Sala Seminari Ovest, Dipartimento Informatica.)

Compressive sensing is a new approach to digital signals acquisition and processing. Its main aim is the reconstruction of sparse signals or images (i.e. with few significant coefficients) from what was previously believed to be incomplete…
