Our choice of discrete nonholonomic constraints on E ( n ) × E ( n ) that mimics the condition of the sphere rolling without slipping over a horizontal plane allows us to construct
Thus, we extended the Lie derivative approach to the study of Hamiltonian operators com- patible with a given Hamiltonian operator P from finite-dimensional Poisson structures [26,
Both algebras are presented by generators and relations, the first has a representation by q -difference operators on the space of symmetric Laurent polynomials in z and the second
In this paper we study the skew divided difference operators with applications to the “Little- wood–Richardson problem” in the Schubert calculus. By the Littlewood–Richardson
Key words: determinants; differential complexes; differential geometry; Einstein metrics; GJMS operators; global invariants; heat kernel; K¨ ahler metrics; Q -curvature; Sobolev
Lichnerowicz’s algebra of differential geometric operators acting on symmetric tensors can be obtained from generalized geodesic motion of an observer carrying a complex
In noncommutative geometry [ 12 ] there is one specific application of the heat kernel expansion which is related to the spectral action principle [ 8 ].. The Dirac operator squared
In our paper we analyze unusual degeneracy properties of energy levels of q,p -oscillators (for real q , p ) and obtain, on their base, certain q -deformed or p -deformed
