杰出青年数学家系列讲座:涂君武 Hodge structures and enumerative invariants of Calabi-Yau categories15:00-17:00

地点:东7报告厅

摘要:We shall review Costello’s definition of Gromov-Witten type invariants in all genus associated with Calabi-Yau A-infinity categories. Then we write down an explicit formula of these invariants in terms of certain stable graphs whose vertices are decorated by ribbon graphs. We give a survey of known calculations of CEI (categorical enumerative invariants). We also report on some of the recent progresses (joint works with Lino Amorim, and Yefeng Shen) in this direction.
