Kunneth formula for Hessian manifolds
Pavel Osipov
We study Dolbeault--Koszul cohomology of flat affine manifolds. We proove a Künneth formula \[ H^{p,q}(M\times N) \cong \bigoplus_{i,j} H^{i,j}(M)\otimes H^{p-i,q-j}(N…
Locally conformally Hessian and statistical manifolds
Pavel Osipov
A statistical manifold is a manifold endowed with a torsion-free connection and a Riemannian metric such that the tensor is totally symmetric…
Statistical Lie algebras of a constant curvature and locally conformally Kähler Lie algebras
Pavel Osipov
We show that a statistical manifold manifold of a constant non-zero curvature can be realised as a level line of Hessian potential on a Hessian cone. We construct a Sasakian struct…
Selfsimilar Hessian and conformally Kähler manifolds
Pavel Osipov
Let be a Hessian manifold. Then the total space of the tangent bundle can be endowed with a Kähler structure . We say that a homogeneou…
Selfsimilar Hessian manifolds
Pavel Osipov
A selfsimiar manifold is a Riemannian manifold endowed with a homothetic vector field . We characterize global selfsimilar manifolds and describe the structur…
Projective Hessian and Sasakian manifolds
Pavel Osipov
The Hessian geometry is the real analogue of the Kähler one. Sasakian geometry is an odd-dimensional counterpart of the Kähler geometry. In the paper, we study the connection betwe…
