The paper is concerned with methods for blowing power of singular cardinals using short extenders. Thus, for example, starting with Ä of coÿnality ! with { ¡ Ä | o( ) ¿ +n } coÿnal in Ä for every n ¡ ! we construct a cardinal preserving extension having the same bounded subsets of Ä and satisfying 2
We show that the number of nontrivial rational points of height at most B, which lie on the cubic surface x 1 x 2 x 3 = x 4 (x 1 + x 2 + x 3 ) 2 , has order of magnitude B(log B) 6 . This agrees with Manin's conjecture.
