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.
