Canonical forms of oriented matroids

Bulletin of the London Mathematical Society, Volume 58, Issue 1, January 2026.
Abstract Positive geometries are semialgebraic sets equipped with a canonical differential form whose residues mirror the boundary structure of the geometry. Every full‐dimensional projective polytope is a positive geometry. Motivated by the canonical forms of polytopes, we construct a canonical form for any tope of an oriented matroid inside the Orlik–

Module structure of Weyl algebras

Journal of the London Mathematical Society, Volume 113, Issue 1, January 2026.
Abstract The seminal paper (Stafford, J. Lond. Math. Soc. (2) 18 (1978), no. 3, 429–442) was a major step forward in our understanding of Weyl algebras. Beginning with Serre's Theorem on free summands of projective modules and Bass' Stable Range Theorem in commutative algebra, we attempt to trace the origins of this work and explain how it led to ...

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.

Third-Order Differential Subordination for Generalized Struve Function Associated with Meromorphic Functions

مجلة بغداد للعلوم
  Previously, many works dealt with the study of the order differential subordination and shortly after that other studies dealt with the  order differential subordination in the unit disc.

Meromorphic functions that share four or three small functions with their difference operators

Advances in Difference Equations, 2019
In this paper, we prove that non-constant meromorphic functions of finite order and their difference operators are identical, if they share four small functions “IM”, or share two small functions and ∞ CM. Our results show that a conjecture posed by Chen–

Borel Directions and Uniqueness of Meromorphic Functions

Abstract and Applied Analysis, 2013
We investigate the relationship between Borel directions and uniqueness of meromorphic functions and obtain some results of meromorphic functions sharing four distinct values IM and one set in an angular domain containing a Borel line.

Algebraic values of meromorphic functions—II

Topology, 1965
AbstractWe continue the study of the possible distributions of numbers at which certain meromorphic functions take on algebraic values. In particular, a 1-parameter subgroup of a linear group or an abelian variety which contains sufficiently many algebraic points must itself be an algebraic subgroup.

Quasinormal Families of Meromorphic Functions

Revista Matemática Iberoamericana, 2005
Let \mathcal{F} be a family of functions meromorphic on the plane domain D , all of whose zeros are multiple. Suppose that f'(z)\ne 1 for all f\in ...
