Path homology of digraphs without multisquares and its comparison with homology of spaces

Xin Fu, Sergei O. Ivanov

For a digraph $G$ without multisquares and a field $F$ , we construct a basis of the vector space of path $n$ -chains $Ω_{n} (G; F)$ for $n \geq 0$ , generalising the bas…

A continuous cusp closing process for negative Kähler-Einstein metrics

Xin Fu, Hans-Joachim Hein, Xumin Jiang

We give an example of a family of smooth complex algebraic surfaces of degree $6$ in $CP^{3}$ developing an isolated elliptic singularity. We show via a gluing construction…
