Pseudorandom sets and explicit constructions of Ramsey graphs
Original language description
We shall show a polynomial time construction of a graph $G$ on $N$ vertices such that $G$ does not contain $K_{r,r}$and$/overline{K}_{r,r}$, for $r=/sqrt{N}/{2^{/epsilon/sqrt{/log N}}}=o(/sqrt{N})$. To this end we construct a subset $X/subseteq F^m$ which has small intersections with all subspaces of dimension $m/2$.

Pseudonáhodné množiny a ramseyovské grafy
Czech description
Ukazujeme casově polynomiální konstrukci grafu $G$ na $N$ vrcholech takovou, že $G$ neobsahuje $K_{r,r}$ ani $/overline {K}_{r,r}$, pro $r=/sqrt{N}/{2^{/epsilon/sqrt{/log N}}}=o(/sqrt{N})$. K tomuto účelu sestrojíme podmnožinu $X/subseteq F^m$, která mámalé průniky se všemi podprostory dimenze $m/2$.
