Objective
Research objectives and content
The project contains two parts which will be pursued simultaneously: A-Geodesics on flat surfaces with singular points B-Zeta function for free groups automorphisms.
In my Ph.D. thesis A-l studied surfaces which are obtained by certain identification of the edges of regular 4g-gon. B-l introduced and computed a zeta function for a large class of free group automorphisms. Goals
A1: Generalize the results of my thesis to more general flat surfaces with singularities.
A2: Describe the geodesics on such surfaces which contain a singularity. A3: Compute or at least estimate the growth function of simple geodesics and of multiple points in dependence of the length
A4: Computing the number, length and homotopy class of the systoles of such surfaces and compute Gromov's isosystolic inequalities. B1: Give an algebraic-dynamic zeta function for all automorphisms of free groups.
B2: Extend the definition to automorphisms of surfaces and word-hyperbolic groups.
B3: Compute efficiently this zeta function and prove ist rationality Training content (objective, benefit and expected impact)

Funding Scheme
Funding scheme (or “Type of Action”) inside a programme with common features. It specifies: the scope of what is funded; the reimbursement rate; specific evaluation criteria to qualify for funding; and the use of simplified forms of costs like lump sums.
