Solving bihomogeneous polynomial systems with a zero-dimensional projection
MatÃas Bender, Laurent Busé, Carles Checa +1
We study bihomogeneous systems defining, non-zero dimensional, biprojective varieties for which the projection onto the first group of variables results in a finite set of points.…

Bigraded Castelnuovo-Mumford regularity and Gröbner bases
MatÃas Bender, Laurent Busé, Carles Checa +1
We study the relation between the bigraded Castelnuovo-Mumford regularity of a bihomogeneous ideal in the coordinate ring of the product of two projective spaces and the bidegr…
