Let $f:M\to N$ be a Morin map. A lift of $f$ is a map $\tilde{f}:M\to N\times\mathbb{R}$ whose composition with the projection $N\times\mathbb{R}\to N$ is $f$. Fold-lift conjecture…

Fold-map cobordism conjecture. There exists a $1$-dimensional linear subspace $\mathfrak G^1\leq\mathfrak N_n$ such that, if $M$ admits a fold map into a stably parallelizable…
