We solve the problem of determining basic topological properties of flat samples by performing measurements on their outer edge. The global maximum of four probe resistances shows a characteristic behaviour, which is dependent on the genus (i.e., the

Let M be a regular map of type { m , n } , with automorphism group a smooth quotient of the ordinary ( 2 , m , n ) triangle group. Then by recent work of Melekoglu and Singerman, we can associate with M some positive integers called the link indices

A closed Riemann surface of genus $$g \geqslant 2$$ is called a Hurwitz curve if its group of conformal automorphisms has order $$84(g-1)$$ . In 1895, Wiman noticed that there is no Hurwitz curve of genus $$g=2,4,5,6$$ and, up to isomorphisms, there

Let p p be a prime and A A a finite group of exponent p p acting by automorphisms on a finite p ′ p’ -group G G . Assume that A A has order at least p 3 p^3 and C G ( a ) C_G(a) is nilpotent of class at most c c for any a ∈ A # a\in A^{\#} . It

The natural automorphism group of a translation surface is its group of translations. For finite translation surfaces of genus g ≥ 2 the order of this group is naturally bounded in terms of g due to a Riemann–Hurwitz formula argument. In analogy

If G is a group of automorphisms of a compact Klein surface X, then the direct product G × C 2 is a group of automorphisms of the Riemann double cover X + of X. In this paper we analyse the relationship between G and the full groups of automorphisms

In this paper we discuss a relationship between the spectral asymmetry and the surface symmetry. More precisely, we show that for every automorphism of a Hurwitz surface with the automorphism group $\text{PSL}(2,\mathbb{F}_{q})$, the $\unicode[STIX]{

In this paper, we introduce the notion of interlacing of Hurwitz series. We begin by reviewing some important properties of the ring of Hurwitz series over a commutative ring A of arbitrary characteristic, and we introduce and investigate properties

In the paper, a discrete universality theorem for the Hurwitz zeta-function ζ ( s , α ) on the approximation of analytic functions by shifts ζ ( s + i τ , α ) when τ takes values from the set { k β h : k = 0 , 1 , … } with fixed 0 β 1 and h
