| Abstract | |
The goal of this paper is to prove the existence of indecomposable rank ((k + 1)(n-k) - (k + 1)) vector bundles on the Grassmannian variety Gr(k, n). We will call them Tango bundles since in the particular case of P-n congruent to Gr(0, n) they correspond to the celebrated vector bundle discovered by H. Tango in 1974. We will give a geometrical description of Tango bundles and we will prove that they are mu-stable. (C) 2015 WILEY-VCH Verlag GmbH \& Co. KGaA, Weinheim (AU) | |
