Explicit Quillen models for Cartesian products of $2$ -cones

Urtzi Buijs, José Carrasquel, Lucile Vandembroucq

We give an explicit minimal Quillen model for the Cartesian product $X \times Y$ of rational $2$ -cones in terms of derivations and a binary operation $\star \colon \mathbb{M}(V)\oti…

Urtzi Buijs, José Carrasquel

In this note we give a characterization of the sectional category of a map between rational spaces in terms of its Koszul-Quillen model.
