We study a classical problem (first posed by Erdős) in the extremal
theory of hypergraphs. According to Erdős, a hypergraph possesses
property $B$ if its set of vertices admits a 2-colouring such
that no edge of the hypergraph is monochromatic. The problem is
to find the minimum $m(n)$ of all $m$
such that there is an $n$-uniform (each edge contains exactly
$n$ vertices) hypergraph with exactly $m$ edges that does not possess
property $B$. We consider more general problems (including the case
of polychromatic colourings) and introduce a number of parametric
properties of hypergraphs. We obtain estimates for analogues
of $m(n)$ for extremal problems on various classes of hypergraphs.
