We study recently meet matrices on meet-semilattices as an abstract generalization of greatest common divisor (GCD) matrices. Analogously, in this paper we consider join matrices on lattices as an abstract generalization of least common multiple (LCM) matrices. A formula for the determinant of join
Let (P , , โง) 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
