The adjacency variety of these entities are used to show which vertices of a graph are adjacent to other vertices. One type of these entities over a commutative ring satisfies its characteristic equation according to the Cayley-Hamilton theorem. One of these constructs containing the I, J, and K components of two vectors as elements can be used to compute the cross product. For n linear equations and n variables, these constructs can be used to represent the equations, and are used to solve the equations for the n variables with Gaussian elimination. For 10 points, name these mathematical cons
