Subellipticity of Some Complex Vector Fields Related to Witten LaplacianWe consider some system of complex vector fields related to the semi-classical Witten Laplacian, and establish the local subellipticity of this system basing on condition (Ψ).李维喜 教授 （武汉大学）腾讯会议室2021年11月23日（星期二） 14:00-14:50

On Complex Structures on Einstein Four-ManifoldsThe question that when a four-manifold with a complex structure admits a compatible Einstein metric has been answered by LeBrun. In this talk, we will discuss some recent progress on the inverse question, namely, when a four-manifold with Einstein me...吴鹏 教授（复旦大学）腾讯会议室2021年11月23日（星期二） 13:00-13:50

Constant Scalar Curvature Kahler Metrics on Ramified Galois CoversLet f: M—>N be a finite ramified Galois cover between compact Kahler manifolds. If N has a cscK metric, under suitable conditions, we shall prove the existence of cscK metrics on M. This generalizes previous works of Arezzo-Ghig...石亚龙 副教授 （南京大学）腾讯会议室2021年11月23日(星期二) 11:00-11:50

Global Solutions of 2D Isentropic Compressible Navier-Stokes Equations with o...We prove the global existence of solutions to the two-dimensional isentropic compressible Navier-Stokes equations with smooth initial data which is slowly varying in one direction and with initial densi...吕勇 副教授 （南京大学）腾讯会议室2021年11月23日（星期二） 10:00-10:50

Anisotropic Minkowski Inequality for Non-Convex DomainsIn this talk, we discuss the anisotropic Minkowski inequality, which is an isoperimetric type inequality between anisotropic mean curvature integral and anisotropic area, for star-shaped F-mean convex domains or outward F-minimizing domains. Ou...夏超 教授 （厦门大学）腾讯会议室2021年11月23日（星期二） 9:00-9:50

Co-Density and Fractional Edge Cover PackingGiven a multigraph G=(V,E), the edge cover packing problem (ECPP) on G is to find a coloring of edges of G using the maximum number of colors such that at each vertex all colors occur. ECPP can be formulated as an integer program and is NP-hard in gen...赵秋兰 副教授 （南京大学）腾讯会议室2021年11月23日（星期二） 8:00-8:50

A Non-Integrated Defect Relation for Meromorphic Maps of Complete Kahler Mani...In this talk, we introduce a non-integrated defect relation for meromorphic maps of a complete Kahler manifold into a complex projective variety intersecting hypersurfaces in su...石磊 博士 （贵州师范大学）腾讯会议室2021年11月21日(星期日) 9：00-11：00

An Index Theorem for End-Periodic Toeplitz OperatorsIn this talk，I will present a recent result on the index theorem for End-Periodic Toeplitz operators. This result can be viewed as a generalization of the theorem by Dai and Zhang for Toeplitz operators on manifolds with boundary and ...李一寒 博士 （陈省身数学研究所）腾讯会议室2021年11月19日（星期五） 10:30-11:30
