Sejal V. Jain M.D.,Sanjeev V. Kothare M.D. (or A*) corresponding to F..,F..,...,F... The matrix A (over the real field) is said to have the property P. if and only if every set of t columns of A is linearly independent. In this paper, for all positive integers q, we obtain necessary conditions on A* such that . (N × 2.) submatrix A** in A h

Near-self-complementary designs and a method of mixed sums,satisfy the relation v=2k, yet for k odd, there are an infinity of parameter sets which cannot be realized as self-complementary designs. For these parameters the idea of near-self-complementary designs is introduced. These designs have many aspects similar to self-complementary designs..An extensio

,On the linear independence of sets of 2q columns of certain (1, −1) matrices with a group structuremore at a time, where the multiplication is assumed commutative, and where F.=μ (the identity element of G) for all j. The elements of G can be written, in order, as {μ; F., ..., F.; F.F.,F.F.,...,F.F.;F.F.F.,...;F.F. ... F.}. Consider a matrix A(N × 2.) over the real field whose columns correspond

On the enumeration of certain graceful graphs,th end points labelled 1 and n has no cycle. Let s. and t. denote the numbers of simple graceful graphs and graceful trees on n vertices respectively. Then t.≦s.≦p(A.) where p(A.) is the permanent (plus determinant) of the (n-2)×(n-2) matrix A.=(a.) defined by: . More specifically, let c. denote the

A note on equidistant permutation arrays,ermutations on . elements, every pair of which is at distance μ. A permutation graph . is a graph with vertex set comprising all permutations on . elements, and edges between each pair of permutations at distance μ. These graphs enable the relevant permutation structure to be visualised; in particul

The combinatorics of algebraic graph theory in theoretical physics,aphs whose generating functions are the physical quantities under investigation. In statistical mechanics there has recently been a trend towards the use of transformations which reduce the complexity of the graphical enumeration at the expense of an increase in algebraic complexity.

Graphs, groups and polytopes,ormation of this polytope onto itself. These observations are used to obtain information on the relation between the automorphism group of X and the multiplicities of the eigenvalues of A. This approach yields new results on this topic as well as improvements of previously known ones.
