(See also a different approach in the unpublished manuscript [ 7 ].) For a Poisson manifold, the modular class coincides up to a factor 2 with the modular class of its cotangent
We study the finite and infinite irreducible representations of the quantum quadratic algebras though the construction of models in which the symmetries act on spaces of functions of
the present application to phantom energy one might try to use the above mechanism to generate standard symmetry break by starting with a graded Lie algebra but using all vector
Review paper [26] contains both general theorems of the symmetry method and classification results on integrable equations: the third and fifth order scalar equations,
The purpose of this paper is to reduce the equations of dispersive flows ( 1 ) and ( 2 ) to complex valued equations by constructing a good moving
We prove an explicit formula for a projection of singular vectors in the Verma module over a rank 2 Kac–Moody Lie algebra onto the universal enveloping algebra of the Heisenberg
In summary, we elaborated a geometric approach to physical theories on spacetimes provided with nonlinear and linear connections compatible with nonsymmetric metrics, in the context
