New moduli components of rank 2 bundles on projective space
We present a new family of monads whose cohomology is a stable rank 2 vector bundle on P-3. We also study the irreducibility and smoothness together with a geometrical description of some of these families. These facts are used to construct a new infinite series of rational moduli components of stab...

Zusammenfassung: | We present a new family of monads whose cohomology is a stable rank 2 vector bundle on P-3. We also study the irreducibility and smoothness together with a geometrical description of some of these families. These facts are used to construct a new infinite series of rational moduli components of stable rank 2 vector bundles with trivial determinant and growing second Chern class. We also prove that the moduli space of stable rank 2 vector bundles with trivial determinant and second Chern class equal to 5 has exactly three irreducible rational components. |
