The spectrum of magnetic Schrödinger operators and $k$ -form Laplacians on conformally cusp manifolds

Sylvain Golénia, Sergiu Moroianu

We consider open manifolds which are interiors of a compact manifold with boundary, and Riemannian metrics asymptotic to a conformally cylindrical metric near the boundary. We show…

On the structure of quantum permutation groups

Teodor Banica, Sergiu Moroianu

The quantum permutation group of the set $X_{n} = {1, ..., n}$ corresponds to the Hopf algebra $A_{a u t} (X_{n})$ . This is an algebra constructed with generators and relations, known to b…

Cusp geometry and the cobordism invariance of the index

Sergiu Moroianu

The cobordism invariance of the index on closed manifolds is reproved using the calculus of cusp pseudodifferential operators on a manifold with boundary. More generally, on a comp…
