Infimumista

Infimumista is a coined term used to describe a person who focuses on the concept of infimum, or greatest lower bound, in mathematics. The word combines infimum with the -ista suffix common in many languages to denote adherents or practitioners. It is informal and not part of standard mathematical nomenclature.

In mathematical use, the infimum of a subset A of a partially ordered set is the greatest element that is less than or equal to every element of A. For real numbers, inf A is the greatest lower bound; it may not be attained by a member of A, in which case the minimum does not exist. The infimum is a fundamental concept in analysis and order theory and is dual to the supremum (greatest upper bound).

The term infimumista often appears in educational contexts, blogs, or forums as a playful label for students or educators who especially emphasize lower bounds, or as a metaphorical stance about seeking the minimal acceptable solution. It should be understood as a humorous or illustrative designation rather than a formal title.

Related concepts include infimum, supremum, minimum, maximum, greatest lower bound, least upper bound, lattice meet operation, and complete lattices.
