A Calogero Model with root string representatives of infinite order Coxeter orbits
Andreas Fring
We present a worked example for the new extensions of the multi-particle Calogero model endowed with infinite Weyl group symmetry of affine and hyperbolic type. Building upon the h…
Lie symmetries and ghost-free representations of the Pais-Uhlenbeck model
Alexander Felski, Andreas Fring, Bethan Turner
We investigate the Pais-Uhlenbeck (PU) model, a paradigmatic example of a higher time-derivative theory, by identifying the Lie symmetries of its associated fourth-order dynamical…
Multisymplectic approach to integrable defects in the sine-Gordon model
Vincent Caudrelier
Ideas from the theory of multisymplectic systems, introduced recently in integrable systems by the author and Kundu to discuss Liouville integrability in classical field theories w…
A multisymplectic approach to defects in integrable classical field theory
V. Caudrelier, A. Kundu
We introduce the concept of multisymplectic formalism, familiar in covariant field theory, for the study of integrable defects in 1+1 classical field theory. The main idea is the c…
Yang-Baxter and reflection maps from vector solitons with a boundary
V. Caudrelier, Q. C. Zhang
Based on recent results obtained by the authors on the inverse scattering method of the vector nonlinear Schrödinger equation with integrable boundary conditions, we discuss the fa…
Graph Zeta Function and Gauge Theories
Yang-Hui He
Along the recently trodden path of studying certain number theoretic properties of gauge theories, especially supersymmetric theories whose vacuum manifolds are non-trivial, we inv…
