Adapted connections with skew-torsion on metric -manifolds
Aleksandra Borówka, Aleksandra Borówka, Ioannis Chrysikos
We provide a natural higher-dimensional generalization of the adapted connections with skew-torsion on almost Hermitian and almost contact metric manifolds presented in \cite{FrIv}…

Complex quaternionic manifolds and c-projective structures
Aleksandra Borówka
We discuss complex quaternionic manifolds, i.e., those that have holonomy , which naturally arise via quaternionic Feix--Kaledin construction. We show that fo…

A note on dual abelian varieties
Aleksandra Borówka, PaweŠBorówka
For any non-principal polarisation , we explicitly construct -polarised abelian variety , such that its dual abelian variety is not (abstractly) isomorphic to . For $\d…
