The (ir)regularity of Tor and Ext
Marc Chardin, Dipankar Ghosh, Navid Nemati
We investigate the asymptotic behaviour of Castelnuovo-Mumford regularity of Ext and Tor, with respect to the homological degree, over complete intersection rings. We derive from a…

Fibers of multi-graded rational maps and orthogonal projection onto rational surfaces
Nicolás Botbol, Laurent Busé, Marc Chardin +1
We contribute a new algebraic method for computing the orthogonal projections of a point onto a rational algebraic surface embedded in the three dimensional projective space. This…
