%0 Journal Article %T On k-simplexes in (2k-1)-dimensional vector spaces over finite fields %A Le Anh Vinh %J Mathematics %D 2009 %I arXiv %X We show that if the cardinality of a subset of the $(2k-1)$-dimensional vector space over a finite field with $q$ elements is $\gg q^{2k-1-\frac{1}{2k}}$, then it contains a positive proportional of all $k$-simplexes up to congruence. %U http://arxiv.org/abs/0903.2506v1
