Málstofa: Gordon Slade

Málstofa 12 september, kl. 10:50 (athugið óvenjulega tímasetningu!) Fyrirlesari: Gordon Slade (University of British Columbia)Titill: Self-avoiding walk, spin systems, and renormalisationÁgrip: The subject of critical phenomena in statistical mechanics is a rich source of interesting and difficult mathematical problems that touch oncombinatorics, probability, and mathematical physics. Self-avoiding walks and lattice spin systems provide fundamental examples. This

Málstofa: Friðrik Freyr Gautason

Næsta málstofa verður þriðjudaginn 21. mars kl 13:20 í Naustinu, húsi Endurmenntunar. Fyrirlesari er Friðrik Freyr Gautason, Háskóla Íslands. Titill fyrirlestrarins er Localization and the AdS/CFT correspondence. Ágrip: When studying quantum systems of particles and their interactions, we are often interested in computing the so-called partition function which is a generating function for physical observables.

Málstofa: Victoria Lynn Martin

Fyrsta málstofa haustsins verður föstudaginn 16. apríl kl 10:30 í Naustinu húsi Endurmenntunar.  Fyrirlesari er Victoria Lynn Martin, Raunvísindastofnun háskólans. Titill hennar er A Selberg zeta function for warped manifolds. Abstract: In this talk I begin by introducing the Selberg zeta function of hyperbolic quotient manifolds (H^3/G, where H^3 is 3-dimensional hyperbolic space and G is a discrete Schottky group) and reviewing a fruitful
