We also give a complete answer to the question of (semi)stability of tangent bundle of all toric Fano 4-folds with Picard number (\\leq) 3 which are classified by Batyrev \\cite{batyrev}. We have constructed a collection of equivariant indecomposable rank 2 vector bundles on Bott tower and pseudo-symmetric toric Fano varieties. Further in case of Bott tower, we have shown the existence of an equivariant stable rank 2 vector bundle with certain Chern classes with respect to a suitable polarization.", "revisions": [ { "version": "v1", "updated": "2019-10-30T16:31:56.000Z" } ], "analyses": { "keywords": [ "equivariant vector bundles", "picard number", "bott tower", "pseudo-symmetric toric fano varieties", "tangent bundle" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
