چکیده

The size of a metric disc embedded in a compact non-orientable hyperbolic surface is bounded by some constant depending only on the genus g ≥ 3. We show that a surface of genus greater than six contains at most one metric disc of the largest radius. For the case g = 3, we carry out an exhaustive study of all the extremal surfaces, finding the location of every extremal disc inside them.

Compact Non-orientable Surfaces of Genus 6 with Extremal Metric Discs

A compact hyperbolic surface of genus g is said to be extremal if it admits an extremal disc, a disc of the largest radius determined only by g. We discuss how many extremal discs are embedded in non-orientable extremal surfaces of genus 6. This is the final genus in our interest because it is already known for g = 3, 4, 5, or g > 6. We show that non-orientable extremal surfaces of genus 6 admi...

Compact Klein Surfaces of Genus 5 with a Unique Extremal Disc

A compact (orientable or non-orientable) surface of genus g is said to be extremal if it contains an extremal disc, that is, a disc of the largest radius determined only by g. The present paper concerns non-orientable extremal surfaces of genus 5. We represent the surfaces as side-pairing patterns of a hyperbolic regular 24-gon, that is, a generic fundamental region of an NEC group uniformizing...

Extremal Isosystolic Metrics for Compact Surfaces

Given a closed, orientable surface M of genus ≥ 2, one seeks an extremal isosystolic metric on M : this is a Riemannian metric that induces on M the smallest possible area, subject to the constraint that the corresponding systole, or shortest length of any non-contractible closed curve, is a fixed, positive number. The geometric problem is rendered into an analytic one by reducing it to solving...

The Asymptotic Dimension of a Curve Graph Is Finite

We find an upper bound for the asymptotic dimension of a hyperbolic metric space with a set of geodesics satisfying a certain boundedness condition studied by Bowditch. The primary example is a collection of tight geodesics on the curve graph of a compact orientable surface. We use this to conclude that a curve graph has finite asymptotic dimension. It follows then that a curve graph has proper...

Lengths of Geodesics on Non-orientable Hyperbolic Surfaces

We give an identity involving sums of functions of lengths of simple closed geodesics, known as a McShane identity, on any non-orientable hyperbolic surface with boundary which generalises Mirzakhani’s identities on orientable hyperbolic surfaces with boundary.
