摘要
We present a new technique for changing the coflnality of large cardinals using homogeneous forcing. As an application we show that many singular cardinals in V can be measurable in HOD. We also answer a related question of Cummings, Friedman and Golshani by producing a model in which every regular uncountable cardinal theta in V is theta(+)-supercompact in HOD.
