Modulus of elementary domains in the hyperbolic plane

Ioannis D. Platis

We study the modulus of curve families inside elementary domains in the hyperbolic plane $\bH^1_\C$. We establish exact expressions for the modulus of connecting and separating cur…

Free and discrete subgroups generated by two quaternionic Heisenberg translations

Sagar B. Kalane, I. D. Platis

Let $A$ and $B$ be two Heisenberg translations of $Sp (2, 1)$ with distinct fixed points. We provide sufficient conditions that guarantee the subgroup $⟨ A, B ⟩$ i…
