An Alternative Definition of the Completion of Metric Spaces
Cheng Hao
In this article, the author proposes another way to define the completion of a metric space, which is different from the classical one via the dense property, and prove the equival…
The nonmeasurability of Bernstein sets and related topics
Cheng Hao
In this article, we shall explore the constructions of Bernstein sets, and prove that every Bernstein set is nonmeasurable and doesn't have the property of Baire. We shall also pro…
Boolean Algebras and Logic
Cheng Hao
In this article we investigate the notion and basic properties of Boolean algebras and prove the Stone's representation theorem. The relations of Boolean algebras to logic and to s…
Maxwell electromagnetic theory from a viewpoint of differential forms
Shenghua Du, Cheng Hao, Yueke Hu +4
In this paper, we discuss the Maxwell equations in terms of differential forms, both in the 3-dimensional space and in the 4-dimensional space-time manifold. Further, we view the c…
