On the number of exact factorization of finite Groups
Jesús Alonso Ochoa Arango, María Angélica Umbarila Martín
In this work, we study the function that counts the number of exact factorizations of a finite group . We compute for some well-known families of finite groups…
On an uncertainty principle for small index subgroups of finite fields
Diego Fernando Díaz Padilla, Jesús Alonso Ochoa Arango
In this paper we continue the study of the nonvanishing minors property (NVM) initiated by Garcia, Karaali and Katz, for the compressed Fourier matrix attached to a subgroup of…
The Automorphisms group of a Current Lie algebra
Jesús Alonso Ochoa Arango, Nadina Elizabeth Rojas
Let be a finite dimensional complex Lie algebra and let be a finite dimensional complex, associative and commutative algebra with unit. We describe the structure…
Double groupoid cohomology and extensions
Jesús Alonso Ochoa Arango, Alejandro Tiraboschi
We study extensions of double groupoids in the sense of \cite{AN2} and show some classical results of group theory extensions in the case of double groupoids. For it, given a doubl…
Multiplier Infinitesimal Bialgebras and Derivator Lie Bialgebras
Jesus Alonso Ochoa Arango, Alejandro Tiraboschi, Shuanhong Wang
We propose a definition of multiplier infinitesimal bialgebra and a definition of derivator Lie bialgebra. We give some examples of these structures and prove that every bibalanced…
On slim double Lie groupoids
Nicolas Andruskiewitsch, Jesus Alonso Ochoa Arango, Alejandro Tiraboschi
We prove that every slim double Lie groupoid with proper core action is completely determined by a factorization of a certain canonically defined "diagonal" Lie groupoid.
