# On $k$-simplexes in $(2k-1)$-dimensional vector spaces over finite fields

Abstract : 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.
