Abstract:

Let l^0 and m^0 be the ideals associated with Laver and Miller forcing, respectively. We show that {\bf add }(l^0) < {\bf cov}(l^0) and {\bf add }(m^0) < {\bf cov}(m^0) are consistent. We also show that both Laver and Miller forcing collapse the continuum to a cardinal \le {\bf h}. - published version (9p)
