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

G-Equivariant Szeg\H{o} Kernel Asymptotics on CR ManifoldsLet $X$ be a compact connected orientable CR manifold of dimension $2n+1$ with non-degenerate Levi curvature, which admits a connected compact Lie group $G$ action. In this talk, we will discuss a Boutet de Monvel-Sj\"ostrand type theor...邵国宽 副教授 (中山大学)腾讯会议室2021年11月19日(星期五) 9:00-10:30
