Janse van Rensburg [ 1 ],[ 2 ] investigated the more general problem considering walks that end somewhere inside the octant, instead of just on the diagonal.. If i is odd the two
If the minimum of the lattice is even, then the dimension of an s-extremal lattices can be bounded by the theory of modular forms.. This shows that such lattices are also extremal
Such a definition is given in section 2 of the present paper; moreover, in Theorem (2.13) we prove that, under some very general conditions on the defining sequence ( a n ), every A ⊆
A publication of the International Linear
For normal operators, it is conjectured that the shell is convex and its closure is polyhedral; the conjecture is proved for indefinite inner product spaces of dimension at most
In this paper, we present some results relating different matrix partial orderings and the reverse order law for the Moore-Penrose inverse and group inverse.. Special attention is
Some generalized inverses of partition matrix and quotient identity of generalized Schur complement.. Some resluts on group inverses of block matrices over
The following example, adapted from [4, Chapter 7], shows that in general the uniform exponential stability is by no means a necessary condition for the existence of a
