✦ Synopsis


It is shown that the shadow of a Sperner family can cover 10 percent of the Boolean algebra. Whether this can be improved to (100 -o(l))% remains open. 1 a91 < c( J2) -=I C' 5 (l-1) holds for every Sperner family 97 This was disproved by Kospanov [8] who

An explicit expression is obtained for the generating series for the number of ramified coverings of the sphere by the torus, with elementary branch points and prescribed ramification type over infinity. This proves a conjecture of Goulden, Jackson, and Vainshtein for the explicit number of such cov

An explicit expression is obtained for the generating series for the number of ramified coverings of the sphere by the double torus, with elementary branch points and prescribed ramification type over infinity. Thus we are able to determine various linear recurrence equations for the numbers of thes
