Modular frobenius manifolds and their invariant flows [PDF]

, 2010
The space of Frobenius manifolds has a natural involutive symmetry on it: there exists a map I which sends a Frobenius manifold to another Frobenius manifold.

Dubrovin's duality for F-manifolds with eventual identities [PDF]

, 2011
A vector field <i>E</i> on an <i>F</i>-manifold (M, o, e) is an eventual identity if it is invertible and the multiplication X*Y := X o Y o E^{-1} defines a new F-manifold structure on <i>M</i>.

From 5d flat connections to 4d fluxes (the art of slicing the cone)

Journal of High Energy Physics, 2023
We compute the Coulomb branch partition function of the 4d N $$ \mathcal{N} $$ = 2 vector multiplet on closed simply-connected quasi-toric manifolds B.

Contact Semi-Riemannian Structures in CR Geometry: Some Aspects

Axioms, 2019
There is one-to-one correspondence between contact semi-Riemannian structures ( η , ξ , φ , g ) and non-degenerate almost CR structures ( H , ϑ , J ) .

Bucshbaum simplicial posets [PDF]

Discrete Mathematics & Theoretical Computer Science, 2014
The family of Buchsbaum simplicial posets generalizes the family of simplicial cell manifolds. The $h'-$vector of a simplicial complex or simplicial poset encodes the combinatorial and topological data of its face numbers and the reduced Betti numbers of

Computing one-dimensional global manifolds of Poincaré maps by continuation [PDF]

, 2005
We present an algorithm to compute one-dimensional stable and unstable manifolds of saddle periodic orbits in a Poincaré section. The computation is set up as a boundary value problem by restricting the beginning and end points of orbit segments to the ...

Fedosov Manifolds [PDF]

, 1997
A. Connection (or parallel transport) is the main object in the geometry of manifolds. Indeed, connections allow comparison between geometric quantities associated with different (distant) points of the manifold.
