Completely Integrable Lax Pair equations for Connes-Kreimer Hopf algebra of rooted trees
Gabriel Baditoiu
We show the complete integrability of the Lax pair equations for certain low-dimensional Lie algebras of the infinitesimal character introduced in the paper \emph{Lax p…
Classification of homogeneous Einstein metrics on pseudo-hyperbolic spaces
Gabriel Baditoiu
We classify the effective and transitive actions of a Lie group on an n-dimensional non-degenerate hyperboloid (also called real pseudo-hyperbolic space), under the assumption…
Spectral geometry of Riemannian Legendre foliations
Gabriel Baditoiu, Stere Ianus, Anna Maria Pastore
We obtain geometric characterizations of isospectral minimal Riemannian Legendre foliations on compact Sasakian manifolds of constant -sectional curvature.
Classification of Pseudo-Riemannian submersions with totally geodesic fibres from pseudo-hyperbolic spaces
Gabriel Baditoiu
We classify pseudo-Riemannian submersions with connected totally geodesic fibres from a real pseudo-hyperbolic space onto a pseudo-Riemannian manifold. Also, we obtain the classifi…
Feynman Diagrams and Lax Pair Equations
Gabriel Baditoiu, Steven Rosenberg
We find a Lax pair equation corresponding to the Connes-Kreimer Birkhoff factorization of the character group of a Hopf algebra. This flow preserves the locality of counterterms. I…
Feynman Diagrams and Lax Pair Equations
Gabriel Baditoiu, Steven Rosenberg
We find a Lax pair equation corresponding to the Connes-Kreimer Birkhoff factorization of the character group of the Hopf algebra of Feynman diagrams. In particular, we obtain a fl…
