Contact detection between an ellipsoid and a combination of quadrics
Miguel Brozos-Vázquez, M. J. Pereira-Sáez, A. B. Rodríguez-Raposo +2
We analyze the characteristic polynomial associated to an ellipsoid and another quadric in the context of the contact detection problem. We obtain a necessary and sufficient condit…
Classification of the relative positions between an ellipsoid and an elliptic paraboloid
Miguel Brozos-Vázquez, María José Pereira-Sáez, María José Souto-Salorio +1
We classify all the relative positions between an ellipsoid and an elliptic paraboloid when the ellipsoid is small in comparison with the paraboloid ({\it small} meaning that the e…
Split -structures and torsion pairs in hereditary categories
Ibrahim Assem, María José Souto Salorio, Sonia Trepode
We give necessary and sufficient conditions for torsion pairs in a hereditary category to be in bijection with -structures in the bounded derived category of that hereditary cat…
Auslander-Buchweitz context and co-t-structures
O. Mendoza, E. C. Saenz, V. Santiago +1
We show that the relative Auslander-Buchweitz context on a triangulated category $\T$ coincides with the notion of co--structure on certain triangulated subcategory of $\T$ (see…
