Simplicial complexes which are minimal Cohen-Macaulay

Yanyan Wang, Tongsuo Wu

Let $\D$ be a $(d - 1)$ -dimensional pure $f$ -simplicial complex over vertex set $[n]$ . In this paper, it is proved that $n = 2 d$ holds true if $\D$ is minimal Cohen-Macaulay. It is als…

Plurisubharmonicity of Bergman Kernels on generalized annuli

Yanyan Wang

Let $A_{ζ} = Ω - ρ (ζ) \cdot Ω$ be a family of generalized annuli over a domain $U$ . We show that the logarithm $lo g K_{ζ} (z)$ of the Bergman kernel $K_{ζ} (z)$ of $A_{ζ}$ is plurisubh…

Variations of Bergman Kernels for Some Explicitly Given Families of Planar Domains

Yanyan Wang

We study the parameter dependence of the Bergman kernels on some planar domains depending on complex parameter ζin nontrivial "pseudoconvex" ways. Smoothly bounded cases are studie…
