Semi compactness and semi-I-compactness in ditopological texture spaces

In this paper we generalize the notion of Semi-continuity and MS-continuity and go on to study Semi-compactness, Semi-cocompactness, Semi-stability and Semi-costability in a ditopological texture space. We also extends the notion of Semi-compactness and Semi-cocompactness to a ditopological texture space modulo an ideal [13].

SEMI $theta$-COMPACTNESS IN INTUITIONISTIC FUZZY TOPOLOGICAL SPACES

The purpose of this paper is to construct the concept of semi$theta$-compactness in intuitionistic fuzzy topological spaces. We give some characterizationsof semi $theta$-compactness and locally semi -compactness. Also, wecompare these concepts with some other types of compactness in intuitionisticfuzzy topological spaces.

Generating photon pulses with an oscillating cavity

– We study the generation of photon pulses from thermal field fluctuations through opto-mechanical coupling to a cavity with an oscillatory motion. Pulses are regularly spaced and become sharp for a high finesse cavity. Photon production from vacuum field fluctuations reflected onto moving boundaries is now a well known phenomenon [1, 2]. For a single moving mirror motion-induced radiation is q...

Localized modes and phonon scattering of a lattice kink.

We consider a discrete sine-Gordon equation with a phase shift. We analyze the stability of a lattice kappa kink which is the ground state of the system. The dependence of the localized mode frequency of a kappa kink on the topological charge is analyzed numerically and analytically. We show that there is a certain range of parameter values for the coupling constant and the phase shift for an i...
