Rationality and categorical properties of the moduli of instanton bundles on the projective 3-space
Mihai Halic, Roshan Tajarod
We prove the rationality and irreducibility of the moduli space of mathematical instanton vector bundles of arbitrary rank and charge on . In particular, the result ap…
On the rationality of the moduli space of instanton bundles on the projective 3-space
Mihai Halic, Roshan Tajarod
We prove the rationality and irreducibility of the moduli space of---what we call---the endomorphism-general instanton vector bundles of arbitrary rank on the projective space. In…
On the -ampleness of the tensor product of two line bundles
Mihai Halic, Roshan Tajarod
We prove that the tensor product of two line bundles, one being -ample and the other with sufficiently low-dimensional base locus, is still -ample.
About the cohomological dimension of certain stratified varieties
Mihai Halic, Roshan Tajarod
We determine an upper bound for the cohomological dimension of the complement of a closed subset in a projective variety which possesses an appropriate stratification. We apply the…
Comparison of certain complexes of modules of generalized fractions and Cech complexes
R. Tajarod, H. Zakeri
We establish an explicit quasi-isomophism of complexes, which is homogeneous in graded situation, from a given Cech complex of modules of generalized fractions.
