Grassman matrices

In mathematics, the Grassmannian Gr(k, V) is a space that parameterizes all k-dimensional linear subspaces of the n-dimensional vector space V. For example, the Grassmannian Gr(1, V) is the space of lines through the origin in V, so it is the same as the projective space of one dimension lower than V. When V is a real or complex vector space, Grassmannians are compact smooth manifolds. In ge… WebSpecifically, a supermatrix is a 2×2 block matrixwith entries in a superalgebra(or superring). The most important examples are those with entries in a commutative superalgebra(such as a Grassmann algebra) or an ordinary field(thought of as …
