Tangent Bundle Filters and Neural Networks: From Manifolds to Cellular Sheaves and Back [PDF]

open access: yesIEEE International Conference on Acoustics, Speech, and Signal Processing, 2022
In this work we introduce a convolution operation over the tangent bundle of Riemannian manifolds exploiting the Connection Laplacian operator. We use this convolution operation to define tangent bundle filters and tangent bundle neural networks (TNNs ...

Stability of the tangent bundle through conifold transitions [PDF]

open access: yesCommunications on Pure and Applied Mathematics, 2021
Let X be a compact, Kähler, Calabi‐Yau threefold and suppose X↦X̲⇝Xt$X\mapsto \underline{X}\leadsto X_t$ , for t∈Δ$t\in \Delta$ , is a conifold transition obtained by contracting finitely many disjoint (−1,−1)$(-1,-1)$ curves in X and then smoothing the ...

BIGNESS OF THE TANGENT BUNDLE OF A FANO THREEFOLD WITH PICARD NUMBER TWO [PDF]

open access: yesNagoya mathematical journal, 2022
In this paper, we study the positivity property of the tangent bundle $T_X$ of a Fano threefold X with Picard number $2$ . We determine the bigness of the tangent bundle of the whole $36$ deformation types.

Fano manifolds with big tangent bundle: a characterisation of $$V_5$$ V 5 [PDF]

open access: yesCollectanea Mathematica, 2021
Let X be a Fano manifold with Picard number one such that the tangent bundle $${{T}_{X}}$$ T X is big. If X admits a rational curve with trivial normal bundle, we show that X is isomorphic to the del Pezzo threefold of degree five.

On the Geometry of the Null Tangent Bundle of a Pseudo-Riemannian Manifold

open access: yesAxioms, 2023
When we consider a non-definite pseudo-Riemannian manifold, we obtain lightlike tangent vectors that constitute the null tangent bundle, whose fibers are lightlike cones in the corresponding tangent spaces.

Some notes on the tangent bundle with a Ricci quarter-symmetric metric connection

open access: yesAIMS Mathematics, 2023
Let $ (M, g) $ be an $ n $-dimensional (pseudo-)Riemannian manifold and $ TM $ be its tangent bundle $ TM $ equipped with the complete lift metric $ ^{C}g $.

Affine transformations of the tangent bundle of a common path space

open access: yesДифференциальная геометрия многообразий фигур, 2023
In this paper, we study infinitesimal transformations of the tangent bundle of a common path space. The general path space is a genera­liza­tion space of the affine connectivity.

Natural Ricci Solitons on Tangent and Unit Tangent Bundles [PDF]

open access: yesZurnal matematiceskoj fiziki, analiza, geometrii, 2021
Considering pseudo-Riemannian $g$-natural metrics on tangent bundles, we prove that the condition of being Ricci soliton is hereditary in the sense that a Ricci soliton structure on the tangent bundle gives rise to a Ricci soliton structure on the base manifold.
