Hello, does anybody know a paper where I can find a proof that K- and L-theory are mackey-functors? -- Marcus Meyer

Can anyone prove my conjecture that loops are Moufang loops if and only if they have the Frobenius conservation property? Moufang loops are Cayley multiplication tables for...

Hi all, Many thanks in advance if you could help to show how Paul Cohen constructed a collection for which AC is required for any of its choice set. ---Nam

Is there anything updated and yet comprehensive in mathematical logic??? Something like Shoenfield's 1967 "Mathematical Logic", but updated with the last 35 years of FOM...

Is there a dense subset S of R^2 such that for every pair of points p,q in S the Euclideean distance d(p,q) is a rational number ? Thanks

what are Bogomolny equations?

The following UBASIC program correctly identifies divisors of phi(N), without having to factor N or know the value of phi(N), for all the values of N that I have tried it on....

Hi all. It seems that the examples (with which I'm familiar) of second-kind linear Fredholm problems are defined either over intervals or over boundaries~$\partial\Omega$,...
