An atomic approach to Shokurov's conic-bundle conjecture
Leonardo F. Cavenaghi, Ludmil Katzarkov, Daniel Pomerleano +1
In this paper, we apply a weaker version of Hodge atoms to show that a standard conic bundle over a smooth complex projective rational surface is irrational if $|2K_S+Δ|\ne\emp…
On the generalized cohomologies of almost abelian solvmanifolds
Mauro de Andrade Pinto, Letícia Camponês do Brasil Maia, Leonardo F. Cavenaghi +1
Generalized complex structures give rise to generalized Dolbeault, Bott--Chern and Aeppli cohomologies. We study these cohomologies for invariant generalized complex structures on…
A quantum connection approach to rationality
Luiz Carazolli, Leonardo F. Cavenaghi, Ludmil Katzarkov +2
We extract rank and regularized exponents from cyclic generic factors of the quantum connection and show that these data persist under the birational comparisons considered here. A…
On the atomic decomposition of complete intersection in flag varieties
Boris Alexeev, Leonardo F. Cavenaghi, Giovane Galindo +3
We develop a root-theoretic localization formalism for genus-zero Gromov--Witten invariants of flag varieties and of smooth zero loci of globally generated homogeneous vector bundl…

Mauro de Andrade Pinto, Letícia Camponês do Brasil Maia, Leonardo F. Cavenaghi +1
We study left-invariant generalized complex structures on almost abelian Lie groups with Lie algebra , where $\mathfrak{h}…
The Cohomology of Solvmanifold SYZ Mirrors
Leonardo F. Cavenaghi, Lino Grama, Ludmil Katzarkov +1
This paper investigates the geometric and cohomological properties of non-Kähler SYZ mirror symmetry for dual torus fibrations over solvmanifolds in the sense of Lau, Tseng and Yau…

This paper introduces a novel framework for constructing invariants in -equivariant birational geometry by unifying two recent approaches: the theory of atoms recently developed…
A Gromov-Witten approach to -equivariant birational invariants
Leonardo F. Cavenaghi, Lino Grama, Ludmil Katzarkov
In arXiv:2404.19088, we initiated a program linking birational invariants with smooth ones and offering new interpretations of classical invariants, such as the Kervaire-Milnor inv…
A Geometric Realization of Spherical T-Duality via -Diagrams
Leonardo F. Cavenaghi, Lino Grama, Ludmil Katzarkov
We relate spherical T-duality for oriented linear -bundles over (the Milnor bundles , which are -principal exactly when or…
Gromoll--Meyer's actions and the geometry of (exotic) spacetimes
Leonardo F. Cavenaghi, Lino Grama
Since the advent of new pairwise non-diffeomorphic structures on smooth manifolds, it has been questioned whether two topologically identical manifolds could admit different geomet…

Leonardo F. Cavenaghi, João Marcos do Ó, Llohann D. Sperança
This paper explores the existence and properties of \emph{basic} eigenvalues and eigenfunctions associated with the Riemannian Laplacian on closed, connected Riemannian manifolds f…
Singular Riemannian Foliations, variational problems and Principles of Symmetric Criticalities
Marcos M. Alexandrino, Leonardo F. Cavenaghi, Diego Corro +1
A singular foliation on a complete Riemannian manifold is called Singular Riemannian foliation (SRF for short) if its leaves are locally equidistant, e.g., the pa…

The family of invariant Riemannian manifolds in the Wallach flag manifold is described by three parameters of positive real numbers. By rest…

Symmetric spaces as adjoint orbits and their geometries
Leonardo F. Cavenaghi, Carolina Garcia, Lino Grama +1
We realize specific classical symmetric spaces, like the semi-Kähler symmetric spaces discovered by Berger, as cotangent bundles of symmetric flag manifolds. These realizations ena…

This paper delves into the concept of ``fat bundles'' within Riemannian submersions. One explores the structural implications of fat Riemannian submersions, particularly focusing o…
A note on the vertizontal curvature of fat bundles

In his unpublished notes on fat bundles, W. Ziller poses a compelling question: given a fat principal -bundle with , and representing…
Fatness and positive curvatures on Riemannian submersions
Leonardo F. Cavenaghi, Lino Grama, Llohann D. Sperança
Guided by rather counterintuitive properties of \emph{dual holonomy fields}, we introduce different notions of \emph{fatness} for Riemannian submersions. We introduce \emph{integra…
Singular Riemannian Foliations and the prescribing scalar curvature problem
Marcos M. Alexandrino, Leonardo F. Cavenaghi
An orbit-like foliation is a singular foliation on a complete Riemannian manifold whose leaves are locally equidistant (i.e., a singular Riemannian foliation) and (transversely…
