On the geometry of WDVV equations and their Hamiltonian formalism in arbitrary dimension

open access: yesJournal of the London Mathematical Society, Volume 114, Issue 4, October 2026.
Abstract It is known that in low dimensions Witten–Dijkgraaf–Verlinde–Verlinde (WDVV) equations can be rewritten as commuting quasilinear bi‐Hamiltonian systems. We extend some of these results to arbitrary dimension N$N$ and arbitrary scalar product η$\eta$.

Symplectic tracking through curved three-dimensional fields by a method of generating functions

open access: yesPhysical Review Accelerators and Beams
Symplectic integrators play a pivotal role in the long-term tracking of charged particles within accelerators. To obtain symplectic maps in accurate simulations of single-particle trajectories, two key components are addressed: precise analytical ...

Critical levels and Jacobi fields in a complex of cycles

open access: yesOsaka Journal of Mathematics, 2013
In this paper it is shown that the space of tight geodesic segments connecting any two vertices in a complex of cycles has finite, uniformly bounded dimension. The dimension is defined in terms of a discrete analogue of Jacobi fields, which are explicitly constructed and shown to give a complete description of the entire space of tight geodesics ...
