Classification of smooth factorial affine surfaces of Kodaira dimension zero with trivial units
Tomasz Pełka, Paweł Raźny
We give a corrected statement of the theorem of Gurjar and Miyanishi, which classifies smooth affine surfaces of Kodaira dimension zero, whose coordinate ring is factorial and has…
A criterion for the existence of periodic points based on the eigenvalues of maps induced in cohomology
Michalina Horecka, Paweł Raźny
We present a criterion for the existence of periodic points based on the eigenvalues of maps induced in cohomology for spaces with rational cohomology isomorphic to a tensor produc…
Invariance of basic Hodge numbers under deformations of Sasakian manifolds
Paweł Raźny
We show that the Hodge numbers of Sasakian manifolds are invariant under arbitrary deformations of the Sasakian structure. We also present an upper semi continuity Theorem for the…
The Solution of Hilbert's Fifth Problem for Transitive Groupoids
Paweł Raźny
In the following paper we investigate the question: when is a transitive topological groupoid continuously isomorphic to a Lie groupoid? We present many results on the matter which…
On the Generalization of Hilbert's Fifth Problem to Transitive Groupoids
Paweł Raźny
In the following paper we investigate the question: when is a transitive topological groupoid continuously isomorphic to a Lie groupoid? We present many results on the matter which…
The Frolicher-type inequalities of foliations
Paweł Raźny
The purpose of this article is to adapt the Frolicher-type inequality to the case of transversely holomorphic and transversely symplectic foliations. These inequalities can be used…
