Balanced metrics and Gauduchon cone of locally conformally Kahler manifolds

Liviu Ornea, Misha Verbitsky

A complex Hermitian $n$ -manifold $(M, I, ω)$ is called locally conformally Kahler (LCK) if $d ω = θ \land ω$ , where $θ$ is a closed 1-form, balanced if $ω^{n - 1}$ is closed, and SKT if $…

Normal form of bimeromorphically contractible holomorphic Lagrangian submanifolds

Ekaterina Amerik, Misha Verbitsky

Let $M$ be a holomorphically symplectic complex manifold, not necessarily compact or quasiprojective, and $X \subset M$ a compact Lagrangian submanifold. We construct a deformation…

Algebraic cones of LCK manifolds with potential

Liviu Ornea, Misha Verbitsky

A complex manifold $X$ is called "LCK manifolds with potential" if it can be realized as a complex submanifold of a Hopf manifold. Let $Y$ its $Z$ -covering, considered as a comple…

Complex curves in hypercomplex nilmanifolds with H-solvable Lie algebras

Yulia Gorginyan

An operator $I$ on a real Lie algebra $A$ is called a complex structure operator if $I^{2} = - I d$ and the $- 1$ -eigenspace $A^{1, 0}$ is a Lie subalgebra in the complexification o…

Non-linear Hopf manifolds are locally conformally Kahler

Liviu Ornea, Misha Verbitsky

A Hopf manifold is a quotient of $C^{n} \0$ by the cyclic group generated by a holomorphic contraction. Hopf manifolds are diffeomorphic to $S^{1} \times S^{2 n - 1}$ and hence do…

Parabolic automorphisms of hyperkahler manifolds

Ekaterina Amerik, Misha Verbitsky

A parabolic automorphism of a hyperkahler manifold is a holomorphic automorphism acting on $H^{2} (M)$ by a non-semisimple quasi-unipotent linear map. We prove that a parabolic automo…

Impact of dissipation ratio on vanishing viscosity solutions of the Riemann problem for chemical flooding model

F. Bakharev, A. Enin, Yu. Petrova +1

The solutions for a Riemann problem arising in chemical flooding models are studied using vanishing viscosity as an admissibility criterion. We show that when the flow function dep…

Closed orbits of Reeb fields on Sasakian manifolds and elliptic curves on Vaisman manifolds

Liviu Ornea, Misha Verbitsky

A compact complex manifold $V$ is called Vaisman if it admits an Hermitian metric which is conformal to a Kähler one, and a non-isometric conformal action by $C$ . It is cal…
