αm-OPEN SETS AND αM-CONTINUOUS FUNCTIONS

Ultrastructural Studies of Human and Rabbit Αm-globulins

Electron micrographs of isolated human alpha(2)M-molecules, obtained by the negative contrast technique, revealed morphologically homogenous structures resembling a graceful monogram of the two letters H and I. The modal values for the length and width of the alpha(2)M particles were 170 A and 100 A, respectively. Purified rabbit alphamacroglobulins contained about 80% alpha(1)M- and 20% alpha(...

CORRECTIONS OF ORDER αm TO S-LEVELS OF HELIUM

Several new corrections of ordermα to the energy levels of S states in helium are obtained from radiative corrections to the Breit potential and from the polarization insertions in the two photon exchange graphs. While individual gauge invariant contributions are comparable to current experimental errors, the sum of these corrections is an order of magnitude smaller due to mutual cancellations....

On Pre-θ-Open Sets and Two Classes of Functions

On supra α open sets and Sα-continuous functions

In this paper we introduce and investigate a new class of sets and functions between topological spaces called supra α-open sets and sα-continuous functions respectively. 2000 Mathematics Subject Classification: 03E72, 54A40

On b-I-Open Sets and b-I-Continuous Functions

One of the important and basic topics in the theory of classical point set topology and several branches of mathematics, which have been researched by many authors, is continuity of functions. This concept has been extended to the setting of I-continuity of functions. Janković and Hamlett [1, 2] introduced the notion of I-open sets in topological spaces. Abd El-Monsef et al. [3] further investi...
