关于树理想

On tree ideals

Martin Goldstern, Miroslav Repicky, Saharon Shelah, Otmar Spinas

摘要:

设l^0和m^0分别是与拉弗强迫和米勒强迫相关的理想。我们证明了add(l^0)< cov(l^0)和add(m^0)< cov(m^0)是一致的。我们还表明,无论是拉弗和米勒强迫塌缩连续的基数<= h。

英文摘要:

Let l^0 and m^0 be the ideals associated with Laver and Miller forcing, respectively. We show that add (l^0) < cov(l^0) and add (m^0) < cov(m^0) are consistent. We also show that both Laver and Miller forcing collapse the continuum to a cardinal <= h .
