MS-36: Generalizations of crystallographic groups and their applications
Invited: Pavel Kalouguine (France), Martin Cramer Pedersen (Denmark) | ||
| Session Abstract | ||
|
Space groups describe the global symmetry of a periodic structure. Generalizations of space groups are often necessary to investigate additional structural features, physical properties or aperiodic structures. These generalizations include superspace groups and chromatic groups (collectively called metacrystallographic groups), groups in non-Euclidean geometries and groupoids. Whereas superspace groups are now part of the daily work of the structural crystallographer, other generalizations are less well known. The microsymposium aims at reviewing these concepts and presenting new results in the field.
