Content and singletons bring unique identification minors
Journal of the Australian Mathematical Society, (2018), doi:10.1017/S1446788718000162
A new class of functions with a unique identification minor is introduced: functions determined by content and singletons. Relationships between this class and other known classes of functions with a unique identification minor are investigated. Some properties of functions determined by content and singletons are established, especially concerning invariance groups and similarity.
