On some properties of the space of minimal prime ideals of 𝐶𝑐 (𝑋)
. In this article we consider some relations between the topological properties of the spaces 𝑋 and 𝑀𝑖𝑛 ( 𝐶 𝑐 ( 𝑋 )) with algebraic properties of 𝐶 𝑐 ( 𝑋 ) . We observe that the compactness of 𝑀𝑖𝑛 ( 𝐶 𝑐 ( 𝑋 )) is equivalent to the von-Neumann regularity of 𝑞 𝑐 ( 𝑋 ) , the classical ring of quotients of 𝐶 𝑐 ( 𝑋 ) . Furthermore, we show that if 𝑋 is a strongly zero-dimensional space, then each contraction of a minimal prime ideal of 𝐶 ( 𝑋 ) is a minimal prime ideal of 𝐶 𝑐 ( 𝑋 ) and in this case 𝑀𝑖𝑛 ( 𝐶 ( 𝑋 )) and 𝑀𝑖𝑛 ( 𝐶 𝑐 ( 𝑋 )) are homeomorphic spaces. We also observe that if 𝑋 is an 𝐹 𝑐 -space, then 𝑀𝑖𝑛 ( 𝐶 𝑐 ( 𝑋 )) is compact if and only if 𝑋 is countably basically disconnected if and only if 𝑀𝑖𝑛 ( 𝐶 𝑐 ( 𝑋 )) is homeomorphic with 𝛽 0 𝑋 . Finally, by introducing 𝑧 ◦ 𝑐 -ideals, countably cozero complemented spaces, we obtain some conditions on 𝑋 for which 𝑀𝑖𝑛 ( 𝐶 𝑐 ( 𝑋 )) becomes compact, basically disconnected and extremally disconnected.
期刊介绍:
Categories and General Algebraic Structures with Applications is an international journal published by Shahid Beheshti University, Tehran, Iran, free of page charges. It publishes original high quality research papers and invited research and survey articles mainly in two subjects: Categories (algebraic, topological, and applications in mathematics and computer sciences) and General Algebraic Structures (not necessarily classical algebraic structures, but universal algebras such as algebras in categories, semigroups, their actions, automata, ordered algebraic structures, lattices (of any kind), quasigroups, hyper universal algebras, and their applications.
