A functional logarithmic formula for hypergeometric functions 3F2

Masanori Asakura, Noriyuki Otsubo

We give a sufficient condition for that the hypergeometric function 3F2 is a linear combination of the logarithmic function. The proof is based on the regulator formula which we pr…

Regulators of K_1 of Hypergeometric Fibrations

Masanori Asakura, Noriyuki Otsubo

We study a deformation of what we call hypergeometric fibrations. Its periods and K_1-regulators are described in terms of hypergeometric functions 3F2 in a variable given by the d…

On the Abel-Jacobi maps of Fermat Jacobians

Noriyuki Otsubo

We study the Abel-Jacobi image of the Ceresa cycle W_k-W_k^-, where W_k is the image of the k-th symmetric product of a curve X on its Jacobian variety. For the Fermat curve of deg…
