There have been many characterizations of the classical curves in PG(2, q) given by the zeros of quadratic and Hermitian forms. The next step is to characterize pencils of such curves. Here it is done in the case that the pencils have a single base point. A key result that emerges from the investiga
Let k, t be positive integers and let 9 be a set-system which consists of k-element sets. In this paper it is proved that one can choose a subsystem 9\* c 9F containing a positive proportion of the members of 9, (i.e. 145\*1 >c(k, t) IsSj) and having the property that every pairwise intersection is
## Abstract It is proved that the variety of relevant disjunction lattices has the finite embeddability property. It follows that Avron's relevance logic **RMI**~min~ has a strong form of the finite model property, so it has a solvable deducibility problem. This strengthens Avron's result that **RM
Some extensions of Fisher's inequality, and applications to clique decompositions. ## Rbumi! A I'aide d'un peu d'algkbre linkaire, nous donnons quelques extensions de l'intgalite de Fisher. Puis, nous appliqbons ces rtsultats aux dtcompositions en cliques de certains graphes.
