TL;DR: The theory of manifolds with affine connection has been studied in this paper, where the authors deal with the theory of conformal, geodesic, and projective mappings and transformations.

Conformal Killing $L^{2}-$forms on complete Riemannian manifolds with nonpositive curvature operator
Sergey Stepanov,Irina Tsyganok +1 more
TL;DR: In this article, a classification of connected complete, locally irreducible Riemannian manifolds with nonpositive curvature operator, which admit a nonzero closed or co-closed conformal Killing L 2 -forms is given.
Journal ArticleDOI
Theorems of existence and of vanishing of conformally killing forms
Sergey Stepanov,Irina Tsyganok +1 more
TL;DR: In this paper, the curvature operator acting on the space of covariant traceless symmetric 2-tensors has been studied on an n-dimensional compact, orientable, connected Riemannian manifold and it has been shown that the dimension of the vector space of conformally Killing p-forms on such a manifold is not zero.
Journal ArticleDOI
On the Sampson Laplacian
TL;DR: In this article, the authors considered the Sampson operator that is a strongly elliptic and self-adjoint second order differential operator acting on covariant symmetric tensors on Riemannian manifolds.
