Topological Lattices

A topological lattice is a mathematical structure combining two ideas: a lattice and topology. A lattice is a set where any two elements have a well-defined "least upper bound" (join) and "greatest lower bound" (meet). When equipped with a topology—a way to define what "close" or "continuous" means—these operations are compatible with this notion of closeness. In simple terms, a topological lattice is a set where elements can be combined or compared smoothly with respect to a structure that allows us to study continuous transformations, making it useful in areas like algebra, analysis, and computer science.
