A gauge theory for the Kadomtsev-Petviashvili system
Anisotropic complex structure on the pseudo-Euclidean Hurwitz pairs
The concept of supercomplex structure is introduced in the pseudo-Euclidean Hurwitz pairs and its basic algebraic and geometric properties are described, e.g. a necessary and sufficient condition for the existence of such a structure is found.
Regular and biregular functions in the sense of Fueter - some problems
The biregular functions in the sense of Fueter are investigated. In particular, the class of LR-biregular mappings (left regular with a right regular inverse) is introduced. Moreover, the existence of non-affine biregular mappings is established via examples. Some applications to the quaternionic manifolds are given.
