N2 - The paper outlines a possible computability-theoretic approach to the theory of Boolean-valued models. We introduce the notion of a decidable Boolean-valued model А. This notion is a natural extension of the classical definition of a decidable structure. Intuitively speaking, in order to formally define А, one needs to (algorithmically) work only with countably many truth values taken from a computable Boolean algebra. This convention allows us to view such А through the lens of computable structure theory.We show that the introduced approach provides a rich class of computable structures. We prove that any possible computable dimension can be realized by an appropriately constructed, decidable Boolean-valued model А. Consequently, there exists a model А having computable dimension 2 (that is, А possesses precisely two computable presentations, up to computable isomorphisms). In contrast, it is known that dimension 2 can be realized neither by a classical decidable structure nor by a computable Boolean algebra.
