Professor Dr. Richard Bruynoghe

In 1921, Richard Bruynoghe and his student Joséph Maisin published on the first use of bacteriophages in a phage therapy context. At that time, Bruynoghe (a medical doctor) was affiliated as a professor at the KU Leuven (Belgium) for just over a decade, within the Bacteriological Institute which he founded and led. After a distinguished career (he was acting mayor of the city of Leuven-Belgium ...

Suucient Conditions for Semicomplete Multipartite Digraphs to Be Hamiltonian Dedicated to Professor Dr. Horst Sachs on His 70th Birthday

A semicomplete multipartite digraph is obtained by replacing each edge of a complete multipartite graph by an arc or by a pair of two mutually opposite arcs. Very recently, Yeo 7] proved that every regular semicomplete multipartite digraph is Hamiltonian. With this, Yeo connrmed a conjecture of C.-Q. Zhang 8]. In the rst part of this paper, a generalization of regularity is considered. We exten...

Dedicated to Professor Yu.i. Manin on His 60th Birthday

Let L = (L, ‖ · ‖v) be an ample metrized invertible sheaf on a smooth quasi-projective algebraic variety V over a number field F . Denote by N(V,L, B) the number of rational points in V having Lheight ≤ B. In this paper we consider the problem of a geometric and arithmetic interpretation of the asymptotic for N(V,L, B) as B → ∞ in connection with recent conjectures of Fujita concerning the Mini...
