Proceedings of the American Mathematical Society, Vol. 125, No. 8 (Aug., 1997), pp. 2245-2254 (10 pages) We construct the so-called right adjoint sequence of an n × n matrix over an arbitrary ring.

Cayley graphs, constructed from the algebraic structure of groups, provide a natural framework for exploring complex combinatorial properties. In these graphs, vertices represent group elements and ...

TheLearningPoint, a self funded venture was recently started by Prashant Bhattacharji. Prashant had a desire to do work that reduces the cost of education as well as expands the reach of educational ...

A Cayley-Sudoku table of a finite group G is a Cayley table for G subdivided into uniformly sized rectangular blocks, in such a way that each group element appears once in each block. Cayley-Sudoku ...

CAYLEY'S often-quoted simile which compares the province of mathematics with “a tract of beautiful country seen at first in the distance, but which will bear to be rambled through and studied in every ...
