On fuzzy subbundles of vector bundles
Published 2003-01-01“…This paper considers fuzzy subbundles of a vector bundle. We define the operations sum, product, tensor product, Hom, and intersection of fuzzy subbundles and in each case, we characterize the corresponding flag of vector subbundles. …”

Combinatorics in N = 1 Heterotic Vacua
Published 2011-01-01“…We briefly review an algorithmic strategy to explore the landscape of heterotic E 8 × E 8 vacua, in the context of compactifying smooth Calabi-Yau threefolds with vector bundles. The Calabi-Yau threefolds are algebraically realised as hypersurfaces in toric varieties, and a large class of vector bundles are constructed thereon as monads. …”

Differential Calculus on N-Graded Manifolds
Published 2017-01-01“…A key point is that the graded derivation module of the structure ring of graded functions on an N-graded manifold is the structure ring of global sections of a certain smooth vector bundle over its body Z. Accordingly, the Chevalley–Eilenberg differential calculus on an N-graded manifold provides it with the de Rham complex of graded differential forms. …”
