to mark the 60th birthday of John Coates, Sarah Zerbes and Vladimir Dok- chitser had produced a diagramme of his mathematical family tree which is included in the volume (next
A conference on Quadratic forms and Related Topics was held at Louisiana State University, Baton Rouge, Louisiana, USA, from March 26 to March 30, 2001.. This meeting was
Thus, by Dirichlet’s Theorem on primes in arithmetic progressions, it follows that there exist infinitely many prime numbers p such that p ≡ a (mod M ). It is clear that these
Our investigation was in part motivated by sequence A049988 in Sloane’s table [ 6 ], that is, the number of arithmetic progressions of positive, integers, nondecreasing with sum
Our objective in this paper is to extend the more precise result of Saias [26] for Ψ( x, y ) to an algebraic number field in order to compare the formulae obtained, and we apply
As part of this investigation, methods are developed, using the tools of algebraic geometry and commutative algebra, to eliminate zero-nonzero patterns A as being potentially

In this light, the aim of the present paper looks natural — to construct an algebraic relation corresponding to a move 3 → 3 on a triangulation of a 4-manifold, and based on
