Staðsetning: Via Zoom. Link to be sent.Tími: Föstudag 25.September kl.10:00 Ágrip: The Bargmann transform is a transform which maps Fourier-invariant function spaces and their duals to certain spaces of formal
[:is] Math colloquium Fyrirlesari: Yadollah Zare, Galatasaray University Titill: Center conditions: pull-back of differential equations. Ágrip: The space of polynomial differential equations of a fixed degree with a center singularity has many irreducible components. We prove that pull-back differential equations form an irreducible component of such a space. This method is inspired by Ilyashenko and Movasati’s

[:is] Math Phys seminar Fyrirlesari: Jakob Björnberg, Chalmers University of Technology Titill: Random permutations and Heisenberg models. Ágrip: We discuss probabilistic representations of certain quantum spin systems, including the ferromagnetic Heisenberg model, in terms of random permutations. Properties of the cycle structure of the random permutations are connected with phase transitions in the spin-system. In
[:is] Math colloquium Fyrirlesari: Lukas Schneiderbauer, Háskóli Íslands Titill: Non-Commutative Geometry: An introduction. Ágrip: This is my attempt to introduce non-commutative geometry to mathematicians. After putting forward the main ideas and main theorem(s), I will concentrate on the construction of simple examples in the context of fuzzy spaces (special cases of non-commutative geometries). In case
