Paper improves volatility forecasting for new issues and spin-offs.
We introduce a notion of secondary characteristic classes of Lie algebra extensions. As a spin-off of our construction we obtain a new proof of Lecomte's generalization of the Chern-Weil homomorphism.
By studying the action of the Weyl group of a simple Lie algebra on its root lattice, we construct torsion free subgroups of small and explicitly determined index in a large infinite class of Coxeter groups. One spin-off is the construction of hyperbolic manifolds of very small volume in up to 8 dimensions.
Study of Morita equivalences in Lie groupoids and their symmetries.
Quantum map counts BPS states in special theories.
A microscopic approach to macroeconomic features is intended. A model for macroeconomic behavior under heterogeneous spatial economic conditions is reviewed. A birth-death lattice gas model taking into account the influence of an economic environment on the fitness and concentration evolution of economic entities is nu…
This research reinterprets Lie and Cartan's work on geometric structures using Lie groupoids.
The present paper deals with mirror symmetry aspects of compact ``barely'' manifolds, that is, manifolds of the form (CY. We propose that the mirror of any barely manifold is another barely one and which is constructed as a fibration of the \emph{mirror} of the CY base. Also,…
New method for constructing real algebraic surfaces from complex tropical hypersurfaces.
