布尔代数(或拓扑)自由积的胞腔性

Cellularity of free products of Boolean algebras (or topologies)

Saharon Shelah

摘要:

如果存在布尔代数B_1,B_2使得c(B_1 x B_2)<= lambda_i但c(B_1 x B_2)> λ da_1 + λ da_2,其中λ da_1 = mu是奇异的,mu > λ da_2 = θ>cf(mu),则我们回答了Monk的问题1

英文摘要:

We answer Problem 1 of Monk if there are Boolean algebras B_1,B_2 such that c(B_i) <= lambda_i but c(B_1 x B_2)> lambda_1+ lambda_2 where lambda_1= mu is singular and mu > lambda_2= theta >cf(mu)
