In this paper we use tight closure and Gro bner basis theory to prove that ladder determinantal rings have rational singularities. We show that the ladder determinantal rings of a certain class of ladders, which we call wide ladders, are F-rational. Though F-rationality is only defined in positive

Blowing up power of a singular cardinalโ€”

The paper is concerned with methods for blowing power of singular cardinals using short extenders. Thus, for example, starting with ร„ of coรฟnality ! with { ยก ร„ | o( ) ยฟ +n } coรฟnal in ร„ for every n ยก ! we construct a cardinal preserving extension having the same bounded subsets of ร„ and satisfying 2
