This paper determined the components of generalized curvature tensor for class Kenmotsu type and established mentioned is {\eta}-Einstein manifold when flat; converse holds true under suitable conditions. It also introduced notion {\Phi}-holomorphic sectional (G{\Phi}SH-) thus found necessary sufficient conditions to be constant G{\Phi}SH-curvature. In addition, {\Phi}-generalized semi-symmetri...

New multichannel descriptors of EEG activity: complexity (omega), total power (zeta) and generalized frequency (phi) were applied to whole night sleep analysis in 11 healthy subjects. The values of omega and phi decreased systematically from waking to slow wave sleep, and increased systematically in consecutive NREM-REM sleep cycles. The changes of zeta were opposite to omega and phi. These des...

Recently‎, some researchers have established some results on existence of endpoints for multivalued mappings. In particular, Mohammadi and Rezapour's [Endpoints of Suzuki type quasi-contractive multifunctions, U.P.B. Sci. Bull., Series A, 2015] used the technique of $alpha-psi$-contractive mappings, due to Samet et al. (2012), to give some results about endpoints of Suzuki type quasi-contractiv...

to start with, having employed transformation wave, some nonlinear partial differential equations have been converted into an ode. then, using the infinite series method for equations with similar linear part, the researchers have earned the exact soliton solutions of the selected equations. it is required to state that the infinite series method is a well-organized method for obtaining exact s...

For every action φ ∈ Hom(G, Autk(K)) of a group G on commutative ring K we introduce two abelian monoids. The monoid Cliffk(φ) consists equivalence classes strongly G-graded algebras type up to Clifford system extensions K-central algebras. $${{\cal C}_k}(\phi )$$ equivariance homomorphisms from the Picard groups (generalized collective characters). Furthermore, for such there is an exact seque...

For a Lipschitz $ \mathbb{Z}- $periodic function \phi:\mathbb{R}\to \mathbb{R}^2 such that \mathbb{R}^2\setminus\{\phi(x):x\in\mathbb{R}\} is not connected, an integer b\ge 2 and \lambda\in (c/{b^{\frac12}},1) $, we prove the following for generalized Weierstrass-type W(x) = \sum\limits_{n 0}^{\infty}{{\lambda}^n\phi(b^nx)} $: box dimension of its graph equal to 3+2\log_b\lambda where c constan...
