in this paper, we introduce the concept of rarely generalized regular fuzzy continuous functions in the sense of a.p. sostak's and ramadan is introduced. some interesting properties and characterizations of them are investigated. also, some applications to fuzzy compact spaces are established.

A generalized quasilinear (GQL) approximation is applied to homogeneous shear turbulence following previous work on the (QL) model. For GQL approximation, velocity fluctuations are decomposed into low- and high-wavenumber groups, former of which solved by considering full nonlinear equations whereas latter obtained from linearized around former.

We classify homogeneous four-dimensional manifolds satisfying a curvature condition which naturally generalizes the Einstein one. Our work leads to new examples of self-similar solutions two-loop renormalization group flow.
