Two non-semisimple quantum invariants of lens spaces

Rhea Palak Bakshi, Mitchell Jubeir, Quinn T. Kolt

We calculate the chromatic spherical invariant $K_{Rep (H)} (L (p, q))$ of lens spaces $L (p, q)$ for arbitrary finite-dimensional unibalanced, unimodular Hopf algebr…

Surjectivity of linear operators and semialgebraic global diffeomorphisms

Francisco Braun, Luis Renato Gonçalves Dias, Jean Venato Santos

We prove that a $C^{\infty}$ semialgebraic local diffeomorphism of $R^{n}$ with non-properness set having codimension greater than or equal to $2$ is a global diffeomorphism…

On global invertibility of semi-algebraic local diffeomorphisms

Francisco Braun, Luis Renato Gonçalves Dias, Jean Venato-Santos

In this partly expository paper we discuss conditions for the global injectivity of $C^{2}$ semi-algebraic local diffeomorphisms $f : R^{n} \to R^{n}$ . In case $n > 2$ , w…
