An S-subalgebra R of A is called S-nice if R∩F = S and the localization of R with respect to S \0 is A. Denoting by W the set of all S-nice subalgebras of A, and defining a notion of open sets on W, one can view W as a T0-Alexandroff space. Thus, the algebraic structure of W can be viewed from the point of view of topology. It is shown that every nonempty open subset of W has a maximal element in it, which is also a maximal element of W. Moreover, a supremum of an irreducible subset of W always exists. As a notable connection with valuation theory, one considers the case in which S is a valuation domain and A is an algebraic field extension of F; if S is indecomposed in A, then W is an irreducible topological space, and W contains a greatest element.}, journal = {International Journal of Mathematical and Computational Sciences}, volume = {15}, number = {3}, year = {2021}, pages = {41 - 45}, ee = {https://publications.waset.org/pdf/10011913}, url = {https://publications.waset.org/vol/171}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 171, 2021}, }
