幾何研討會

主講者: 莊武諺博士 (Rutgers University, US)
講題: BPS invariants and wallcrossing
時間: 2010-02-26 (Fri.)  15:00 - 16:00
地點: 數學所 609 研討室 (台大院區)
Abstract: In this talk we discuss the BPS invariants in physics/string theory and their wallcrossing under the variations of the stability conditions. We will also mention the connection with the generalized Donaldson-Thomas invariants. Some concrete examples like the resolved conifold will be discussed. New results of higher rank DT invariants will be also presented if time permits.
