A Tannakian approach to dimensional reduction of principal bundles [PDF]
, 2016 Let $P$ be a parabolic subgroup of a connected simply connected complex semisimple Lie group $G$. Given a compact K\"ahler manifold $X$, the dimensional reduction of $G$-equivariant holomorphic vector bundles over $X\times G/P$ was carried out by the first and third authors.

Clifford structures, bilegendrian surfaces, and extrinsic curvature [PDF]
arXiv, 2023 We use Clifford algebras to construct a unified formalism for studying constant extrinsic curvature immersed surfaces in riemannian and semi-riemannian $3$-manifolds in terms of immersed bilegendrian surfaces in their unitary bundles. As an application, we provide full classifications of both complete and compact immersed bilegendrian surfaces in the ...

Some families of big and stable bundles on $K3$ surfaces and on their Hilbert schemes of points [PDF]
arXiv, 2021 Here we investigate meaningful families of vector bundles on a very general polarized $K3$ surface $(X,H)$ and on the corresponding Hyper--Kaehler variety given by the Hilbert scheme of points $X^{[k]}:= {\rm Hilb}^k(X)$, for any integer $k \geqslant 2$. In particular, we prove results concerning bigness and stability of such bundles.

Two preferential conducting pathways within the bundle of His of the dog heart.
The Japanese Journal of Physiology, 1975 An isolated preparation formed exclusively of the specific conducting tissue of the A. V. node, bundle of His and bundle branches was dissected from the dog heart and studied using the microelectrode technique.

On the stability of syzygy bundles [PDF]
arXiv, 2009 We are concerned with the problem of the stability of the syzygy bundles associated to base point free vector spaces of forms of the same degree d on the projective space of dimension n. We deduce directly, from Mark Green's vanishing theorem for Koszul cohomology, that any such bundle is stable if his rank is sufficiently high. With a similar argument,

Generalized Cheeger-Gromoll Metrics and the Hopf map [PDF]
arXiv, 2008 We show, using two different approaches, that there exists a family of Riemannian metrics on the tangent bundle of a two-sphere, which induces metrics of constant curvature on its unit tangent bundle. In other words, given such a metric on the tangent bundle of a two-sphere, the Hopf map is identified with a Riemannian submersion from the universal ...

Revista Colombiana de Cardiología, 2010 Se conoce que la estimulación en el ápex del ventrículo derecho produce disincronía ventricular y muchas veces los pacientes desarrollan miocardiopatía dilatada, lo que ha llevado a realizar una estimulación más fisiológica.
