A B 2-sequence is a sequence a 1 < a 2 < · · · < ar of positive integers such that the sums a i + a j , 1 ≤ i ≤ j ≤ r, are different. When q is a power of a prime and θ is a primitive element in GF (q 2) then there are B 2-sequences A(q, θ) of size q with aq < q 2 , which were discovered by R. C. Bose and S. Chowla. In Theorem 2.1 I will give a faster… (More)

The independent sets of an algebraic matroid are sets of algebraically independent transcendentals over a field k. If a matroid M is isomor-phic to an algebraic matroid the latter is called an algebraic representation of M. Vector representations of matroids are defined similarly. A matroid may have algebraic (resp. vector) representations over fields of… (More)
