On ultraproducts of Boolean algebras and irr

Anotated Content §1 Consistent inequality [We prove the consistency of irr(i<κ B i /D) < i<κ irr(B i)/D where D is an ultrafilter on κ and each B i is a Boolean Algebra. This solves the last problem of this form from the Monk's list of problems in [M2], that is number 35. The solution applies to many other properties, e.g. Souslinity.] §2 Consistency for small cardinals [We get similar results ...

On the (non-)equivalence of IRR and NPV

The internal rate of return (IRR) is generally considered inferior to the net present value (NPV) as a tool for evaluating and ranking projects, despite its inherently useful comparability to the cost of capital and the return of other investment opportunities. We introduce the ‘‘selective IRR’’, a return criterion which, as a selection of an extended set of possible IRRs, is NPV-consistent. Th...

Kpc Trails of Ionized Gas behind Two Irr Galaxies in A1367

In a 6h Hα exposure of the N-W region of the cluster of galaxies A1367 we discovered a 75 kpc cometary emission of ionized gas trailing behind two Irregular galaxies. The Hα trails correspond in position and length with tails of syncrotron radiation. At the galaxy side opposite to the tails the two galaxies show bright HII regions aligned along arcs, where the star formation takes place at the ...
