Its equivalent contrapositive form has biological implications. Our goal is to provide an extension of Shih-Dong's theorem into all finite distributive lattices. Our method of proof is based on Shih-Dong's “collective effect method” as well as G. Birkhoff's representation theorem for finite distributive lattices.離散動態系統有限分配格固定點廣義布爾雅可比矩陣負迴路正迴路Discrete dynamical systemFinite distributive latticeFixed pointGeneralized Boolean Jacobian matrixNegative circuitPositive circuit
