Topological properties of closed ${\tilde{\mathrm{G}}}_2$, $\mathrm{SL}(3;\mathbb{C})$ and $\mathrm{SL}(3;\mathbb{R}{)}^2$ forms on manifolds

Laurence H. Mayther

This paper uses algebro-topological techniques such as characteristic classes and obstruction theory, together with the $h$-principles for ${\tilde{\mathrm{G}}}_2$ and $\mathrm{S…
