Abstract

Using an algebraic orbifold method, we present non-commutative aspects of G2G_2 structure of seven dimensional real manifolds. We first develop and solve the non commutativity parameter constraint equations defining G2G_2 manifold algebras. We show that there are eight possible solutions for this extended structure, one of which corresponds to the commutative case. Then we obtain a matrix representation solving such algebras using combinatorial arguments. An application to matrix model of M-theory is discussed.
