On K3 surfaces with hyperbolic automorphism groups
Koji Fujiwara, Keiji Oguiso, Xun Yu
We show the finiteness of the Néron-Severi lattices of complex projective K3 surfaces whose automorphism groups are non-elementary hyperbolic with explicit descriptions, under the…

Hardy-Littlewood maximal operator on spaces of exponential volume growth
Koji Fujiwara, Amos Nevo
We consider the Hardy-Littlewood maximal function associated with ball averages on spaces with exponential volume growth. We focus on discrete groups with balls defined by invarian…

Shearing coordinates and convexity of length functions on Teichmueller space
M. Bestvina, K. Bromberg, K. Fujiwara +1
We prove that there are Fenchel-Nielsen coordinates for the Teichmueller space of a finite area hyperbolic surface with respect to which the length functions are convex.
