The notion of S S-algebra is introduced. The theory of apolarity and generic canonical forms for polynomials is generalized to S S-algebras over the complex field β«.ήβ¬ We apply this theory to the problem of finding the essential rank of general, symmetric, and skew-symmetric tensors.

β¦ Synopsis
Each graph may be associated with a certainfunction called its genericform. If one knows the generic forms of given graphs, then one can easily determine the number of spanning trees in graphs obtained from a complete multi-graph either (1) by adding, or (2) by deleting the edges of disjoint copies of the given graphs. Our objective here is to give a proof of a simple and useful relation between the generic forms of graphs that are complementary with respect to a complete multi-graph.

A regular self-complementary graph is presented which has no complementing permutation consisting solely of cycles of length four. This answers one of Kotzig's questions.
Let {HiL,.,,,. ,x be an isomorphic factorization of K,. If there is a permutation p on V(K.) such that /j': V(H,)+ V(H,+ ,) is an isomorphism for i= 1,2, , k-1, then a graph isomorphic to Hi is called a cyclically k-complementary graph. In this paper, some theorems are presented to prove the exist
## Abstract The linear vertexβarboricity Ο(__G__) of a graph __G__ is defined to be the minimum number of subsets into which the vertex set of __G__ can be partitioned such that each subset induces a linear forest. In this paper, we give the sharp upper and lower bounds for the sum and product of l
## Abstract It is shown that certain conditions assumed on a regular selfβcomplementary graph are not sufficient for the graph to be strongly regular, answering in the negative a question posed by Kotzig in [1].
