INFINITESIMAL CHEREDNIK ALGEBRAS AS W-ALGEBRAS
, 2016 In this article we establish an isomorphism between universal infinitesimal Cherednik algebras and W-algebras for Lie algebras of the same type and 1-block nilpotent elements.

From infinitesimal harmonic transformations to Ricci solitons [PDF]
, 2013 summary:The concept of the Ricci soliton was introduced by R. S. Hamilton. The Ricci soliton is defined by a vector field and it is a natural generalization of the Einstein metric.

CL-Transformation on 3-Dimensional Quasi Sasakian Manifolds and Their Ricci Soliton
MathematicsThis paper explores the geometry of 3-dimensional quasi Sasakian manifolds under CL-transformations. We construct both infinitesimal and CL-transformation and demonstrate that the former does not necessarily yield projective killing vector fields.

European Physical Journal C: Particles and FieldsIn the present article, we introduce Q-solitons, a generalization of Riemann solitons, on (almost) coKähler manifolds (ACKM, in short). Here we obtain a necessary condition from which we establish that a compact ACKM admitting Q-soliton whose soliton ...

On infinitesimal conformal and projective transformations of normal contact spaces
Tohoku Mathematical Journal, 1962 Introduction. In the previous paper [ 4 ]° the author discussed some properties of normal contact spaces. However, problems concerning infinitesimal transformations have not been studied. In the present paper such problems are concerned and some satisfactory answers are given. In § 1, we state the fundamental identities of normal contact spaces. In § 2,

H-contact semi-Riemannian manifolds [PDF]
, 2013 We characterize H-contact semi-Riemannian manifolds (i.e., contact semi-Riemannian manifolds whose Reeb vector field ξ is harmonic) by the condition that ξ is a Ricci eigenvector. We then investigate how H-contact semi-Riemannian manifolds are related to

Parabolic quasi-contact cone structures with an infinitesimal symmetry [PDF]
We interpret the property of having an infinitesimal symmetry as a variational property in certain geometric structures. This is achieved by establishing a one-to-one correspondence between a class of cone structures with an infinitesimal symmetry and ...
