DOI: 10.1007/jhep04(2018)087

Abstract: A bstractWe analyze heterotic line bundle models on elliptically fibered Calabi-Yau three-folds over weak Fano bases. In order to facilitate Wilson line breaking to the standard model group, we focus on elliptically fibered three-folds with… read more here.

DOI: 10.1007/s10711-019-00436-2

Abstract: An ACM bundle on a polarized algebraic variety is defined as a vector bundle whose intermediate cohomology vanishes. We are interested in ACM bundles of rank one with respect to a very ample line bundle… read more here.

DOI: 10.1080/00927872.2017.1319476

Abstract: ABSTRACT In this paper, for any simple, simply connected algebraic group G of type A and for any maximal parabolic subgroup P of G, we provide a criterion for a Richardson variety in G∕P to… read more here.

DOI: 10.1142/s0129167x21500865

Abstract: We investigate the deformations of pairs [Formula: see text], where [Formula: see text] is a line bundle on a smooth projective variety [Formula: see text], defined over an algebraically closed field [Formula: see text] of… read more here.
