Almost Kähler 4-dimensional Lie groups with $J$-invariant Ricci tensor [PDF]
arXiv, 2003 The aim of this paper is to determine left-invariant strictly almost K\"ahler structures on 4-dimensional Lie groups $(g, J, \Omega)$ such that the Ricci tensor is $J$-invariant.

The moduli space of 6-dimensional 2-step nilpotent Lie algebras [PDF]
arXiv, 2003 We determine the moduli space of metric 2-step nilpotent Lie algebras of dimension up to 6. This space is homeomorphic to a cone over a 4-dimensional contractible simplicial complex.

A conjectural Lefschetz formula for locally symmetric spaces [PDF]
arXiv, 2004 We formulate a conjectural Lefschetz formula for locally symmetric spaces of finite volume. The formula can be verified in the compact case and for Riemann surfaces.
