(One-value) graph magma algebras are algebras having a basis B = V boolean OR {1} such that, for all u,v is an element of V, uv is an element of {u,0}. Such bases induce graphs and, conversely, certain types of graphs ...

The affine group scheme of automorphisms of an evolution algebra ε with ε 2 is shown to lie in an exact sequence → D → Aut(E) → S, where D, diagonalizable, and S, constant, depend solely on the directed graph associated ...

O objetivo deste trabalho é apresentar métodos de álgebra linear para a resolução de alguns problemas relacionados ao problema de reconstrução de grafos por vertex-switching de Stanley (1985). O Lema de ...

In this work we present the minimum cut method for the detection of communities in graphs, we illustrate the method with examples and we propose an work routine such that the math teacher could apply communities detection ...

Precalculation covers a variety of math problems from algebra to trigonometry, regularly associated with the use of functions or graphing algebraic equations , linear inequalities , logarithms and exponentials.
