In this paper, we introduce a new approach to the generation of binary sequences by applying trace functions to elliptic curves over GF 2m . We call these sequences elliptic curve...

The relational data model is based on sets of tuples, i.e. it does not allow duplicate tuples in a relation. Many database languages and systems do require multi-set place, the hi...

Every 3-graph in which no four vertices are independent and no four vertices span precisely three edges must have edge density 4/9(1 - o(1)). This bound is tight. The proof is a r...
