Morse functions and Real Lagrangian Thimbles on Adjoint Orbits
Elizabeth Gasparim, Luiz A. B. San Martin
We compare Lagrangian thimbles for the potential of a Landau-Ginzburg model to the Morse theory of its real part. We explore Landau-Ginzburg models defined using Lie theory, constr…

Differentiability of Lyaupnov Exponents
Thiago F. Ferraiol, Luiz A. B. San Martin
We prove differentiability of certain linear combinations of the Lyapunov spectra of a flow on a principal bundle of a semi-simple Lie group. The specific linear combinations that…
