Combinatorial zeta functions counting triangles
Journal of Topology, Volume 19, Issue 2, June 2026.Abstract In this paper, we compute special values of certain combinatorial zeta functions counting geodesic paths in the (n−1)$(n-1)$‐skeleton of a triangulation of an n$n$‐dimensional manifold. We show that they carry a topological meaning. As such, we recover the first Betti and L2$L^2$‐Betti numbers of compact manifolds, and the linking number of ...

Determination of poles of sectionally meromorphic functions [PDF]
, 1986 The numerical methods of Abd-Ellal, Delves and Reid for locating poles of meromorphic functions inside smooth closed contours C in the complex plane are generalized to apply to sectionally meromorphic functions satisfying a homogeneous or nonhomogeneous ...

A Note on Unique Range Sets of Meromorphic Functions with Deficient Values
, 2016 [[abstract]]With the help of the notion of weighted sharing of sets we deal with the problem of Unique Range Sets for meromorphic functions and obtain a result which improve some previous ...

Starlike meromorphic functions
, 1972 In this paper we study meromorphic univalent functions which map the unit disk onto the exterior of a domain which is starlike with respect to some finite point different from the origin.

On unicity of meromorphic functions due to a result of Yang - Hua [PDF]
, 2007 summary:This paper studies the unicity of meromorphic(resp. entire) functions of the form $f^nf^{\prime }$ and obtains the following main result: Let $f$ and $g$ be two non-constant meromorphic (resp.

Convex and starlike meromorphic functions
, 1980 In this paper we study meromorphic univalent functions with a simple pole at p which map the unit disk onto the exterior of convex sets or the exterior of starlike sets. A question raised by Libera and Livingston concerning the equality of two classes of

Sufficient conditions for meromorphic starlikeness and close-to-convexity of order α
International Journal of Mathematics and Mathematical Sciences, 2001 The object of the present paper is to derive a property of certain meromorphic functions in the punctured unit disk. Our main theorem contains certain sufficient conditions for starlikeness and close-to-convexity of order α of meromorphic functions.
