The index of conformal Hopf maps

Eric Loubeau, Radu Slobodeanu

We compute the index and nullity of any harmonic morphism from $S^{3}$ to $S^{2}$ .

Flows of geometric structures II

Daniel Fadel, Udhav Fowdar, Eric Loubeau +2

We advance the general theory of flows of tensorial $H$ -structures, focusing on non-isometric flows and on the case $H = SU (m) \subset SO (2 m)$ . Afte…

Topology of isometric classes and flows of geometric structures

Daniel Fadel, Eric Loubeau

We revisit flows of tensorial $H$ -structures for closed and connected Lie subgroups $H ⩽ SO (n)$ , focusing on the topology of isometric classes. We prove that the nat…
