The Geometry and Topology of Singular CurvesFibration is one of the most important tools to classify algebraic surfaces and to study moduli spaces. Singular fibers play an important role in the classifaction of fibrations. Many fibrations with remarkable arithmetic and geometric properties can ...龚成 副教授（苏州大学）腾讯会议室2021年12月11日（星期六） 10:15-11:15

Gamma Conjecture I for Del Pezzo SurfacesConjecture O and the Gamma conjectures for Fano manifolds were proposed by Galkin, Golyshev and Iritani. Conjecture O is concerned with eigenvalues of an operator on the quantum cohomology of X induced by the quantum multiplication by the first Chern class...李长征 教授（中山大学）腾讯会议室2021年12月11日（星期六） 9:00-10:00

On Smooth Complex Surfaces of General Type with Minimal Holomorphic Euler Cha...I will give a brief introduction to complex smooth surfaces of general type with holomorphic Euler characteristic χ(O) = 1. A complete classification of such sur- faces is still missing. I will foc...陈伊凡 副教授（北京航空航天大学）腾讯会议室2021年12月10日（星期五） 10:15-11:15

Problems in Algebraic Theory Related to Lawson HomologyWe will review basic materials about the theory of algebraic cycles over the field of complex numbers and Lawson homology. Then we will talk about some interested problems (and their relations) of in the algebraic cycle theory in terms of the...胡文传 教授（四川大学）腾讯会议室2021年12月10日（星期五） 9:00-10:00

The I-Quantum Group U^I(N)I will report on a second paper with Yadi Wu. This paper investigates the i-quantum group U^i(n) and their associated q-Schur algebra of type C. I will make comparisons between the i-quantum groups U^j(n) and U^i(n) and q-Schur algebras S^j(n,r) and S^i(n,r) of type ...杜杰 教授（新南威尔士大学）腾讯会议室2021年12月10日（星期五） 9:00-10:00
