(with J. Aguilera and P. Schlicht) A determinacy transfer theorem for sigma-projective sets of reals

We prove that determinacy for $\sigma$-projective games of length $\omega$ implies the determinacy of a large class of games of length $\omega^2$. In the process, we obtain a new proof of $\sigma$-projective determinacy for games of countable length from large cardinals.

A preprint of this paper will be uploaded here soon.
