Closed manifold surgery obstructions and the Oozing Conjecture

Ian Hambleton, Ozgun Unlu

We complete the description of surgery obstructions up to homotopy equivalence for closed oriented manifolds with finite fundamental group. New examples are presented of non-trivia…

Stabilization and costabilization with respect to an action of a monoidal category

Mehmet Akif Erdal, Özgün Ünlü

We study actions of monoidal categories on objects in a suitably enriched $2$ -category, and applications in stable homotopy theory. Given a monoidal category $I$ and an $…

Free Actions of Extraspecial $p$ -Groups on $S^{n} \times S^{n}$

Ian Hambleton, Ozgun Unlu

Let $p$ be an odd regular prime, and let $G_{p}$ denote the extraspecial $p$ --group of order $p^{3}$ and exponent $p$ . We show that $G_{p}$ acts freely and smoothly on $S^{2p-1} \times…
