NOTES ON SYMMETRIC CONFORMAL GEOMETRIES
In this article, we summarize the results on symmetric conformal geometries. We review the results following from the general theory of symmetric parabolic geometries and prove several new results for symmetric conformal ge...

Symmetric difference on posets with an antitone involution
The concept of symmetrical difference is defined for arbitrary posts having an antitone involution. In the case of lattices a very natural description of symmetrical difference follows. Sufficieant conditions for the existence of

SYMMETRIC PARABOLIC CONTACT GEOMETRIES AND SYMMETRIC SPACES
We discuss parabolic contact geometries carrying a smooth system of symmetries. We show that there is a symmetric space such that the parabolic geometry (G -> M, w) is a fibre bundle over this symmetric space if and only if the b...

States on symmetric logics: extensions
We continue the study of symmetric logics, i.e., collections of subsets generalizing Boolean algebras and closed under the symmetric difference. We contribute to several open questions. One of them is whether there is a non-Boolean ...
