Weyl and Zariski chambers on projective surfaces
Krishna Hanumanthu, Nabanita Ray
Let be a nonsingular complex projective surface. The Weyl and Zariski chambers give two interesting decompositions of the big cone of . We study these two decompositions and…
Negative curves on special rational surfaces
Marcin Dumnicki, Lucja Farnik, Krishna Hanumanthu +4
We study negative curves on surfaces obtained by blowing up special configurations of points in the complex projective palne. Our main results concern the following configurations:…
Real and complex supersolvable line arrangements in the projective plane
Krishna Hanumanthu, Brian Harbourne
We study supersolvable line arrangements in over the reals and over the complex numbers, as the first step toward a combinatorial classification. Our main results s…
Positivity of vector bundles on homogeneous varieties
Indranil Biswas, Krishna Hanumanthu, D. S. Nagaraj
We study the following question: Given a vector bundle on a projective variety such that the restriction of to every closed curve is ample, under what con…
Bounded negativity and Harbourne constants on ruled surfaces
Krishna Hanumanthu, Aditya Subramaniam
Let be a smooth projective surface and let be an arrangement of curves on . The Harbourne constant of was defined as a way to investigate the occ…
Rationality of Seshadri constants on general blow ups of
Łucja Farnik, Krishna Hanumanthu, Jack Huizenga +2
Let be a projective surface and let be an ample line bundle on . The global Seshadri constant of is defined as the infimum of Seshadri constants $\v…
