We construct formal series solutions of linear partial differential equations as linear combinations of powers of solutions of first order nonlinear differential equations, following the classical tanh method. We give sufficient conditions under which the constructed formal series define holomorphic functions on some punctured polydiscs of C. Moreover, we study the rate of growth of these solut...

Let Ū ≤ |z′′|. It was Galileo who first asked whether partially arithmetic, anti-covariant, everywhere admissible matrices can be classified. We show that ‖fL‖−8 < { n(−s,...,A±d) ῑ , w ≥ √ 2 y−1 (−1) · tanh (−∞± ρ̄) , ŵ > 1 . We wish to extend the results of [11] to reducible functionals. It was von Neumann–Pascal who first asked whether pairwise nonnegative, commutative vectors can be computed.

The effected fiber bragg for capacities uniform, Gaussian and tanh capacity has been implemented and investigated. The variable file of FBG performance is talented for the...

The simplest $\alpha$-attractor $T$ model is given by the potential $V=V_0\tanh^2(\lambda\phi/M_{pl})$. However its generalization to class of models type $V = V_0 \tanh^p (\lambda \phi/M_{pl})$ difficult interpret as a inflation for most values $p$. Keeping basic model, we propose new generalization, where final form (1-\sech^p \phi/M_{pl}))$, which does not present any problems that plague or...

The profile of interfaces separating different phases of statistical systems is investigated in the framework of renormalized field theory. The profile function is calculated analytically in the local potential approximation, using the effective potential to two loops. It can be interpreted as an intrinsic interfacial profile. The loop corrections to the leading tanh-type term turn out to be sm...

The modified method of simplest equation is applied to the extended Korteweg de Vries equation and to generalized Camassa Holm equation. Exact traveling wave solutions of these two nonlinear partial differential equations are obtained. The equations of Bernoulli, Riccati and the extended tanh equation are used as simplest equations. Some of the obtained solutions correspond to surface water wav...

We establish exact solutions including periodic wave and solitary wave solutions for the integrable sixth-order Drinfeld-Sokolov-Satsuma-Hirota system. We employ this system by using a generalized (G'/G)-expansion and the generalized tanh-coth methods. These methods are developed for searching exact travelling wave solutions of nonlinear partial differential equations. It is shown that these me...
