Let (P , , โˆง) be a locally finite meet semilattice. Let S = {x 1 , x 2 , . . . , x n }, x i x j โ‡’ i j, be a finite subset of P and let f be a complex-valued function on P . Then the n ร— n matrix (S) f , where is called the meet matrix on S with respect to f . The join matrix on S with respect to f
