On numerical semigroups with embedding dimension four

Kazimierz Chomicz ยท 2026

We develop a geometric procedure for finding the Ap\'ery set of any numerical semigroup with embedding dimension four. We use this method to find the Frobenius numbers, genera, Betti elements, minimalโ€ฆ

Bordisms and unbounded $KK$-theory

Robin J. Deeley, Magnus Goffeng, Bram Mesland ยท 2026

This monograph studies $KK$-theory in its unbounded model. The central object is the $KK$-bordism group obtained by imposing the $KK$-bordism relation on unbounded $KK$-cycles. In the paradigm of noncโ€ฆ
