Transverse Hilbert schemes and completely integrable systems
Complex Manifolds, 2017 In this paper we consider a special class of completely integrable systems that arise as transverse Hilbert schemes of d points of a complex symplectic surface S projecting onto ℂ via a surjective map p which is a submersion outside a discrete subset of ...

On holomorphically projective mappings of parabolic K\"ahler manifolds
, 2017 In this paper we study fundamental equations of holomorphically projective mappings of parabolic Kähler spaces (which are generalized classical, pseudoand hyperbolic Kähler spaces) with respect to the smoothness class of metrics.

On the mobility degree of (pseudo-) Riemannian spaces with respect to concircular mappings
, 2013 In this paper we study the mobility degree of (pseudo-) Riemannian spaces with respect to concircular mappings. We assume that the smoothness class of differentiability is C .

The second Betti number of hyperk\"ahler manifolds [PDF]
, 2015 Let $M$ be a compact irreducible hyperkahler manifold, from Bogomolov inequality [V1] we obtain forbidden values of the second Betti number $b_2$ in arbitrary dimension.

Holonomy groups of pseudo-quaternionic-K\"ahlerian manifolds of non-zero scalar curvature
, 2010 The holonomy group $G$ of a pseudo-quaternionic-K\"ahlerian manifold of signature $(4r,4s)$ with non-zero scalar curvature is contained in $\Sp(1)\cdot\Sp(r,s)$ and it contains $\Sp(1)$.

Abelian simply transitive affine groups of symplectic type [PDF]
, 2001 We construct a model space $C(\gsp(\bR^{2n}))$ for the variety of Abelian simply transitive groups of affine transformations of type ${\rm Sp}(\bR^{2n})$.

A Nearly Quaternionic Structure on SU(3)
, 2009 It is shown that the compact Lie group SU(3) admits an Sp(2)Sp(1)-structure whose distinguished 2-forms $\omega_1,\omega_2,\omega_3$ span a differential ideal. This is achieved by first reducing the structure further to a subgroup isomorphic to SO(3)

Hyperk\"ahler Manifolds of Curves in Twistor Spaces [PDF]
, 2014 We discuss hypercomplex and hyperk\"ahler structures obtained from higher degree curves in complex spaces fibring over ${\mathbb{P}}^1$.Comment: v4: added the missing assumption on dimension in Theorem 3 ...
