## Abstract In this paper we investigate Boolean algebras and their subalgebras in Alternative Set Theory (AST). We show that any two countable atomless Boolean algebras are isomorphic and we give an example of such a Boolean algebra. One other main result is, that there is an infinite Boolean alge

โฆ Synopsis
Studxes of various algebraic structures which can be defined over a Boolean algebra by means of Boolean operations have been made by Bernstein [1,2], Cunkle [3], Elliott [4], Frink [6, 7], Gratzer [8], Gratzer and Schmidt [9], Rudeanu [ 10, 11 ], Valdyanathaswamy [12], Wiener [13], and others. The first determination of all ring structures was made by Frlnk [7] m 1928. The subclass of Boolean tings has been investigated independently by Gratzer and Schmldt [9], Rudeanu [10, 1 I], and Gratzer [8]. The mvestxgation of these topics Is summarized and completed here, the principal new contributions covering homomorphlsms and lsomorphlsms between the rings
