We introduce two axioms in Laguerre geometry and prove that they provide a characterization of miquelian planes over fields of the characteristic different from 2. They allow to de…

A construction of a skewaffine structure in Laguerre geometry
Andrzej Matras'
J. Andre constructed a skewaffine structure as a group space of a normally transitive group. In the paper this construction was used to describe such an external structure associat…
