Constructive mathematics and unbounded operators — A reply to Hellman
It is argued that Hellman's arguments purporting to demonstrate that constructive mathematics cannot cope with unbounded operators on a Hilbert space are seriously flawed, and that there is no evidence that his thesis is correct.
R.Devi et al. [4] introduced the concept of $g\~$$\alpha$-open sets. In this paper, we introduce and study some properties of functions with ultra $g\~$$\alpha$-closed graphs and strongly $g\~$$\alpha$-closed graphs by utilizing $g\~$$\alpha$-open sets and the eg-closure operator.
