Hyper-extensions of $\sigma $-algebras
Zdeněk Frolík · Czech digital mathematics library · 1973
A new operation "measurably discrete" union is introduced, and for any r -algebra two &~ algebras Jhd and ttCL (z^Jhd) are introduced and the extension of two-valued measures is investigated.For an extension theorem for real valued measures two similar hyper-extensions h^CL and H H & are introduced.The results were discussed in my 1970-71 seminar, and they were announced in my talk at the 3rd Prague Symposium in Topology and its Applications* Kftf WCTflg find PtaTMfg* extension of a C-algebra, extension of measures, hyper-rocks, regular measures, measurable cardinal* AMS, Primary 28A05 Ref .2. % 51?
