## Abstract An (__n,k,p,t__)‐lotto design is an __n__‐set __N__ and a set ${\cal B}$ of __k__‐subsets of __N__ (called blocks) such that for each __p__‐subset __P__ of __N__, there is a block $B \in {\cal B}$ for which $\left | P \cap B \right | \geq t$. The lotto number __L(n,k,p,t)__ is the small

We investigate the existence and multiplicity of weak solutions u 2 W 1;p 0 ðOÞ to the degenerate quasilinear Dirichlet boundary value problem where z 2 R is a parameter. It is assumed that 1opo1; p=2; and O is a bounded domain in R N : The number l 1 stands for the first (smallest) eigenvalue of t
The largest class of multivalued systems satisfying the ring-like axioms is the Hv-ring. In this paper we study a wide class of Hv-rings resulting from an arbitrary ring by using the P-hyperoperations. We reduce the number of those structures by using isomorphisms derived by translations with respec
