Published Papers

 
Representaions of Path Algebras with Applications to Subgroup Lattices and Group Characters(jointly worked)
Iiyori Nobuo and Masato Sawabe
Tokyo Journal of Mathematics   37(1) 37-59   2014   [Refereed]
Let Tex be a quiver, and Tex a weight function on the set of arrows of Tex. In this paper, we will introduce an Tex-algebra Tex over a ring Tex in which the information how vertices of Tex are joined by its arrows with weights should be r...
Simplicial complexes associated to quivers arising from finite groups(jointly worked)
Nobuo Iiyori, Masato Sawabe
Osaka journal of mathematics   52(1) 161-204   Jan 2015   [Refereed]
In this paper, we will introduce a simplicial complex Tex defined by a quiver Tex and a family Tex of paths in Tex. We call Tex a path complex of Tex in Tex. Let Tex be a finite group, and denote by Tex and ${\rm Co...
Partially ordered sets of non-trivial nilpotent Tex-subgroups.
Sawabe, Masato
Osaka Journal of Mathematics   53(3) 731-750   Jul 2016   [Refereed]
We introduce a subposet Tex of a poset Tex of all non-trivial nilpotent Tex-subgroups of a finite group Tex. We examine basic properties of a subgroup in Tex which contains the notion of both a radical Tex-subgro...
A New Characterization of Some Simple Groups by Order and Degree Pattern of Solvable Graph.
B. Akbari, A. R. Moghaddamfar
A New Characterization of Some Simple Groups by Order and Degree Pattern of Solvable Graph   45(3) 337-363   Nov 2016   [Refereed]
The solvable graph of a finite group Tex, denoted by&0a;Tex, is a simple graph whose vertices are the prime divisors of Tex and two distinct primes Tex and Tex are joined by an edge if and only if there exists a solvable subgro...
Homology of a certain associative algebra(jointly worked)
46(1) 1-30   2017   [Refereed]
Let A be a associative R-algebra posessing an R-basis B. We introduce a homology H_n (A,B) and we develop a general theory of H_n (A,B). Some example of H_n (A,B) are also provided.
