[:is] Math colloquium Fyrirlesari: Gestur Ólafsson, Louisiana State University Titill: Atomic decomposition of Bergman spaces on Hermitian Symmetric Spaces Staðsetning: Zoom link will be sent by emailTími: Þriðjudag 16.febrúar kl. 16:00 Ágrip: Hermitian symmetric spaces, bounded or unbounded, and spaces of functions or distributions on those spaces show up naturally in com- plex analysis, Lie

[:is] Math colloquium Fyrirlesari: Anders Karl Claesson, Háskóli Íslands Titill: On the problem of Hertzsprung and similar problems Staðsetning: Via Zoom. Link to be sent.Tími: Þriðjudag 19.janúar kl.10:00 Ágrip: Drawing on a problem posed by Hertzsprung in 1887 (sometimes called the n-kings problem), we say that a permutation w contains the Hertzsprung pattern u if

[:is] Math colloquium Fyrirlesari: Elisa Domínguez-Hüttinger, Universidad Nacional Autónoma de México Titill: A “triple-switch” hybrid mathematical model of epidermal homeostasis. Staðsetning: Via Zoom. Link to be sent.Tími: Föstudag 13.nóvember kl.14:00 Ágrip: The epidermis is the outermost layer of the skin. It is a stratified epithelium, constituted by layers of epithelial cells (keratinocytes) with increasing levels

[:is] Math colloquium Fyrirlesari: Adam Timar, Háskóli Íslands Titill: Uniform Spanning Forests of infinite graphs. Staðsetning: Via Zoom. Link to be sent.Tími: Föstudag 30.október kl.10:00 Ágrip: Consider a spanning tree of a given finite graph, chosen uniformly at random. The so-defined Uniform Spanning Tree (UST) has long been an object of interest, since it is

[:is] Math colloquium Fyrirlesari: Kristján Jónasson, University of Iceland. Titill: Maximum likelihood estimation of multivariate normal parameters when values are missing. Staðsetning: Via Zoom. Link to be sent.Tími: Föstudag 18.September kl.10:00 Ágrip: I have been working on a program to estimate the covariance matrix of a multivariate normal distribution in the presence of missing values

[:is] Math colloquium Fyrirlesari: Bobby Cheng, University of Sussex, UK Titill: Quantum Resonances in Relativistic Systems. Staðsetning: Via Zoom. Link to be sent.Tími: Föstudag 9.október kl.10:00 Ágrip: Significant amounts of research have been completed on mathematical quantum resonances in the non-relativistic setting. However success in generalizing these results to the relativistic setting have been limited. In

[:is] Math colloquium Fyrirlesari: Peter Giesl, University of Sussex, UK Titill: Existence and construction of a contraction metric as solution of a matrix-valued PDE. Staðsetning: Via Zoom. Link to be sent.Tími: Föstudag 2.október kl.10:00 Ágrip: A contraction metric is a Riemannian metric, with respect to which the distance between adjacent solutions of an ordinary differential

[:is] Math colloquium Fyrirlesari: Joachim Toft , Department of mathematics, Faculty of Technology, Linnæus University, Växjö, Sweden Titill: Analytic pseudo-differential calculus via the Bargmann transform. 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
