GROUPOIDS AND IRREVERSIBLE DISCRETE DYNAMICAL SYSTEMS II [PDF]
Fiabilitate şi Durabilitate, 2012 The purpose of this paper is to study the topology of the orbit space of an irreversible discrete dynamical system (X, ) seen as a principal groupoid associated to the groupoid G(X,,E) introduced in [1] (where E is an equivalence relation on X).

Holomorphic field theories and higher algebra
Bulletin of the London Mathematical Society, Volume 57, Issue 10, Page 2903-2974, October 2025.Abstract Aimed at complex geometers and representation theorists, this survey explores higher dimensional analogs of the rich interplay between Riemann surfaces, Virasoro and Kac‐Moody Lie algebras, and conformal blocks. We introduce a panoply of examples from physics — field theories that are holomorphic in nature, such as holomorphic Chern‐Simons ...

Whiskered Groupoids and Crossed Modules with Diagrams
Journal of New TheoryIn this study, we investigate the relationships between the category of crossed modules of groups and the category of whiskered groupoids. Our first aim is to construct a crossed module structure over groups from a whiskered groupoid with the objects set

The conjugacy problem for ascending HNN‐extensions of free groups
Proceedings of the London Mathematical Society, Volume 131, Issue 4, October 2025.Abstract We give an algorithm to solve the Conjugacy Problem for ascending HNN‐extensions of free groups. To do this, we give algorithms to solve certain problems on dynamics of free group endomorphisms.

Universal connections on Lie groupoids
International Journal of Mathematics and Mathematical Sciences, 2003 Given a Lie groupoid Ω, we construct a groupoid J1Ω equipped with a universal connection from which all the connections of Ω are obtained by certain pullbacks.

Graph Varieties Axiomatized by Semimedial, Medial, and Some Other Groupoid Identities
Discussiones Mathematicae - General Algebra and Applications, 2020 Directed graphs without multiple edges can be represented as algebras of type (2, 0), so-called graph algebras. A graph is said to satisfy an identity if the corresponding graph algebra does, and the set of all graphs satisfying a set of identities is ...

Journal für die reine und angewandte Mathematik (Crelles Journal), 2015 Abstract We construct and describe a family of groupoids over complex curves which serve as the universal domains of definition for solutions to linear ordinary differential equations with singularities. As a consequence, we obtain a direct, functorial method for resumming formal solutions to such equations.

Surveys in Mathematics and its Applications, 2006 The purpose of this paper is to recall the main ingredients of the construction of the C*-algebra of a groupoid (introduced by Renault in [A groupoid approach to C*-algebras, Lecture Notes in Math., Springer-Verlag, 793, 1980]) and to collect some ...

Journal of New Theory, 2014 In this paper, Smarandache soft groupoids shortly (SS-groupoids) are introduced as a generalization of Smarandache Soft semigroups (SS-semigroups) . A Smarandache Soft groupoid is an approximated collection of Smarandache subgroupoids of a groupoid .

Strict Deformation Quantization via Geometric Quantization in the Bieliavsky Plane
Abstract and Applied Analysis, 2020 Using standard techniques from geometric quantization, we rederive the integral product of functions on ℝ2 (non-Euclidian) which was introduced by Pierre Bieliavsky as a contribution to the area of strict quantization.
