The cardinality conjecture for spaces generated by sigma-sets

About 17 years old · traced to

Let IN={1,2,3,…}IN=\{1,2,3,\ldots\}, let IN⋆={1∗,2∗,3∗,…}IN^{\star}=\{1^{\ast},2^{\ast},3^{\ast},\ldots\}, and let INΘ={1Θ,2Θ,3Θ,…}IN_{\Theta}=\{1_{\Theta},2_{\Theta},3_{\Theta},\ldots\}. For a set SS, write 2S2^S for its power space, and let ⟨2X∪Y,2X∪Y⋆⟩\langle 2^{X\cup Y},2^{X\cup Y^{\star}}\rangle denote the space generated by these two spaces. The cardinality conjecture. For all X∈2INΘX\in 2^{IN_{\Theta}} and Y∈2INY\in 2^{IN},

∣⟨2X∪Y,2X∪Y⋆⟩∣=2∣X∣3∣Y∣.|\langle 2^{X\cup Y},2^{X\cup Y^{\star}}\rangle|=2^{|X|}3^{|Y|}.

The conjecture proposes a cardinality formula for spaces generated by two sigma-sets and is intended to establish new relationships involving infinite cardinals within sigma-Set Theory. The paper provides only foundations and does not report a resolution.
