The aim of this paper is to introduce a new class of sets called (i,j) r^g closed sets and a new class of maps called D^(i,j) continuous maps and D^(i,j)irresolute maps in bitopological spaces. Also we introduce some new spaces called (i,j) – T^1/2 , (i,j) ^T 1/2 ,*T^1/2, ^T*1/2 and ^Trg and obtain their basic properties. Mathematics Subject Classification: 54A10

An influence of the magnetized electron positron plasma on a process of neutrino propagation is investigated. A total contribution of all crossed processes, νe → νe, νe → νe, ν → νee, νee → ν, is found for the first time, which appears not to depend on the chemical potential of electron-positron gas. Relatively simple expressions for the probability and mean losses of the neutrino energy and mo...

It has been pointed out that a TeV e−e− linear collider may be unique in probing new physics in the weak isospin I = 2 channel for the longitudinalWW scattering1,2 W− L W − L → W− L W− L . Even if there is no resonance in this channel, a stronglyinteracting electroweak sector (SEWS) may still yield a sufficiently large signal rate. However, the continuum standard model (SM) backgrounds are subs...

Using the idea of ic-open sets, we introduce and investigate topological qualities an ic-closure, ic-interior, ic-limit points, ic-derived, ic-border, ic-frontier, ic-exterior a set. Introduce concepts "ic-continuous mappings," "ic-open "ic-irresolute "ic-totally continuous "ic-homeomorphism," then look into some properties these mappings
