Twisted Poincaré Lemma and Twisted Čech-de Rham Isomorphism in case of Projective Line
Ko-Ki Ito
In this paper, we give a direct proof of the twisted Poincaré lemma by using the integrations over regularized paths. This method tells us a concrete description of the Čech-de Rha…

The Elliptic Hypergeometric Functions Associated to the Configuration Space of Points on an Elliptic Curve I : Twisted Cycles
Ko-Ki Ito
We consider the Euler type integral associated to the configuration space of points on an elliptic curve, which is an analogue of the hypergeometric function associated to the conf…
