Extending Nearaffine Planes to Hyperbola Structures

Similarity:
H. A. Wilbrink [Geom. Dedicata 12 (1982)] considered a class of Minkowski planes whose restrictions, called residual planes, are nearaffine planes. Our study goes in the opposite direction: what conditions on a nearaffine plane are necessary and sufficient to get an extension which is a hyperbola structure.

On some properties of -planes of type-2 fuzzy sets
Zdenko Takáč (2013)
Kybernetika
Similarity:
Some basic properties of -planes of type-2 fuzzy sets are investigated and discussed in connection with the similar properties of -cuts of type-1 fuzzy sets. It is known, that standard intersection and standard union of type-1 fuzzy sets (it means intersection and union under minimum t-norm and maximum t-conorm, respectively) are the only cutworthy operations for type-1 fuzzy sets. Recently, a similar property was declared to be true also for -planes of type-2 fuzzy sets in a few...
Some Generalization of Nearaffine Planes

Similarity:
There are three kinds of Benz planes: Möbius planes, Laguerre planes and Minkowski planes. A Minkowski plane satisfying an additional axiom is connected with some other structure called a nearaffine plane. We construct an analogous structure for a Laguerre plane. Moreover, our description is common for both cases.
