Funktionaalianalyysin seminaari

Seminar in Functional Analysis

Kari Astala, Hans-Olav Tylli ja Xiao Zhong

torstai/Thursday 12-14 C124 (Exactum, 1. krs.)

Funktionaalianalyysin seminaari kokoontuu perinteiseen tapaan kevätlukukaudella 2017. Seminaarin aihepiirissä on monipuolisesti esillä funktionaalianalyysi ja sen sovellukset, erityisesti analyysin kysymyksiin ja inversio-ongelmiin. Aiheista käsitellään sekä ajankohtaisia tutkimusongelmia että yleistajuisia perusasioita ("kaikkien pitäisi tätä ehdottomasti osata").

Seminaariin osallistuva henkilökunta ohjaa (funktionaali)analyysiin ja sen sovelluksiin liittyviä pro graduja, lisensiaattitutkielmia ja väitöskirjoja.

Tervetuloa !
