P(om)/fin及其平方的分配数
The distributivity numbers of of P(om) /fin and its square
摘要:
我们证明了在Mathias强迫h(2)的长度为ω_2的可数支撑迭代强迫下,r.o.(P(omega)/fin)^2是omega_1,但P(omega)/fin之一h是omega_2。
英文摘要:
We show that in a model obtained by forcing with a countable support iteration of length omega_2 of Mathias forcing h(2), the distributivity number of r.o.(P(omega)/fin)^2, is omega_1 but h, the one of P(omega)/fin, is omega_2.
