The upcoming talk
At the next session of the TCS,
on the 5th of March 2025,
at 2:15 – 4:15 p.m. CET / 3:15 – 5:15 p.m. EET
Katarzyna Grabowska
(KMMF WFUW)
shall talk about
“Dirac algebroids in Hamiltonian and Lagrangian dynamics – theory and examples“.
Abstract
Dirac algebroid is a linear Dirac structure defined on the dual of a vector bundle. We propose the construction of a Dirac algebroid associated with constraints and use it as a tool for generating the dynamics from Lagrangian and Hamiltonian. This structure is very general. It allows for all types of generating functions, including these with magnetic-like terms as well as singular. At the end of the talk we shall propose topics for future research related to the subject.
