Rank-two weak Fano bundles on a four-dimensional quadric hypersurface
Yuta Takahashi
We classify rank weak Fano bundles on a four-dimensional smooth quadric hypersurface . Up to twisting with a line bundle, such a bundle is either a split bundle, a spinor…
A linear lower bound on the Ulrich complexity of hypersurfaces
Angelo Felice Lopez, Debaditya Raychaudhury, Yuta Takahashi
We give a lower bound on the Ulrich complexity of hypersurfaces in terms of their dimension.
Varieties with Ulrich exterior powers of the tangent bundle
Yuta Takahashi, Kiwamu Watanabe
We study smooth polarized projective varieties whose exterior powers of the tangent bundle are Ulrich. We prove that if is -Ulrich for some …
Weak Fano bundles of rank over hyperquadrics of dimension
Yuta Takahashi
A vector bundle whose projectivization becomes a weak Fano variety is called a weak Fano bundle. We present classification results for rank 2 weak Fano bundles on higher-dimensiona…
Quotients in super-symmetry: formal supergroup case
Yuta Takahashi, Akira Masuoka
We describe the structure of the quotient of a formal supergroup by its formal sub-supergroup . This is a consequence which…
Fano -folds with nef tangent bundle in positive characteristic
Yuta Takahashi, Kiwamu Watanabe
In characteristic , the Campana-Peternell conjecture claims that the only smooth Fano variety with nef tangent bundle should be homogeneous. In this paper, we study the positive…
