[Turkmath:7522] Galatasaray Seminerleri

[Muhammed Uludag]

Notice that this week there will be two seminars.

Oleg BELEGRADEK à 15h (Bilgi Üniversitesi)
*Title. How similar can non-isomorphic algebraic structures be?*

Abstract. In this talk (oriented to a general mathematical audience not
necessarily familiar with model theory) I will discuss the notion of
elementary equivalence, one of the basic notions of model theory,
illustrating it with various algebraic examples, both classical and more
recent. In particular, some author's results on model-theoretic
properties of unitriangular groups will be discussed.


Eric SOCCORSI à 16h30 (centre de physique théorique, Marseille)
*Title. Lipschitz stability in an inverse problem for non autonomous
magnetic Schrödinger equations.*

Abstract. We consider the inverse problem of determining the time
dependent magnetic field of the Schrödinger equation in a bounded open
subset of R^n, n>=1, from a finite number of Neumann data, when the
boundary measurement is taken on an appropriate open subset of the
boundary. We prove the Lispchitz stability of the magnetic potential in
the Coulomb gauge class by n times changing initial value suitably.
