Partial Integrability of Almost Complex Structures on Thurston Manifolds
Oleg Mushkarov, Christian L. Yankov
We prove that any left-invariant symplectic almost complex structure on a Thurston manifold which is compatible with its canonical left-invariant Riemannian metric has holomorphic…

Contact twistor spaces and almost contact metric structures
Johann Davidov, Christian L. Yankov
The notions of a twistor space of a contact manifold and a contact connection on such a manifold have been introduced by L. Vezzoni as extensions of the corresponding notions in th…

On the Convex Closure of the Graph of Modular Inversions
Mizan R. Khan, Igor E. Shparlinski, Christian L. Yankov
In this paper we give upper and lower bounds as well as a heuristic estimate on the number of vertices of the convex closure of the set $$ G_n=\left\{(a,b) : a,b\in \Z, ab \equiv 1…
