On Riemann Surfaces of genus g with 4g automorphisms

E. Bujalance, A. F. Costa, M. Izquierdo

We determine, for all genus $g \geq 2$ the Riemann surfaces of genus $g$ with $4 g$ automorphisms. For $g \neq =$ $3, 6, 12, 15$ or $30$ , this surfaces form a real Riemann surface $\mathcal…

Escherlike quasiperiodic heterostructures

A. G. Barriuso, J. J. Monzon, L. L. Sanchez-Soto +1

We propose quasiperiodic heterostructures associated with the tessellations of the unit disk by regular hyperbolic triangles. We present explicit construction rules and explore som…
