Hahn Decomposition Theorem of Signed Lattice Measure

Abstract

In this paper, we will define a signed Lattice measure on $\sigma$-algebras, as well as give the definition of positive and negative Lattice. Herein, we will show that the Hahn Decomposition Theorem decomposes any space X into a positive lattice A and a negative Lattice B such that $A\vee B$ =X and the signed Lattice measure of $A\wedge B$ is 0.
