Oscillation for quasilinear elliptic equations with p(x)-Laplacians in general domains

Electronic Journal of Differential Equations, 2013
Oscillation of quasilinear elliptic equations with p(x)-Laplacians in general domains are derived by the variational approach as applications of Picone identity. Three examples are given, and generalizations to quasilinear elliptic equations with $p(x)

On inner product quasilinear spaces and hilbert quasilinear spaces

, 2016
In this paper, we state some properties of inner product quasilinear spaces. Moreover we introduce the concepts of inner product Ω-space, Hilbert Ω-space and investigate some related theorems. Also, we establish some differences of inner product quasilinear spaces from the inner product (linear ...

Finite-time blow-up in a quasilinear fully parabolic attraction-repulsion chemotaxis system with density-dependent sensitivity

Electronic Journal of Differential Equations
This article concerns the quasilinear fully parabolic attraction-repulsion chemotaxis system $$\displaylines{ u_t=\nabla \cdot ((u+1)^{m-1}\nabla u -\chi u(u+1)^{p-2} \nabla v + \xi u(u+1)^{p-2}\nabla w),\quad x \in \Omega,\; t >0,\cr v_t=\Delta v+\alpha

Multiple solutions for a nonhomogeneous quasilinear sub-elliptic system with critical growth and logarithmic perturbation

Demonstratio Mathematica
The interest of this paper is that we use the critical point theory to prove the existence of a sequence of non-trivial solutions for a class of nonhomogeneous quasilinear Sub-elliptic systems with critical growth and logarithmic perturbation.

Soft quasilinear operators in soft normed quasilinear spaces

Journal of Intelligent & Fuzzy Systems, 2023
In this study, we define soft quasilinear functionals on soft normed quasilinear spaces and we examine some of its qualities. By using the soft quasilinear operator defined in [6] we specify and prove some theorem related to the continuity and boundedness of soft quasilinear operators and functionals.

Quasilinearization and approximate quasilinearization for lidstone boundary value problems

International Journal of Computer Mathematics, 1992
Quasilinearization technique has been applied to a general nonlinear Lidstone boundary value problem for the construction of a sequence of its approximate solutions {xn (t)}. Sufficient conditions for the linear as well as quadratic convergence of {xn (t)} to the unique solution x ∗(t) of the boundary value problem have been provided.

Quasilinear varieties of semigroups

Semigroup Forum, 2009
A semigroup variety \(\mathcal V\) is called `quasilinear' if for each word \(w\) there is a linear word \(w'\) such that \(\mathcal V\) satisfies \(w\approx w'\). If for each word \(w\) we have a unique \(w'\) then we obtain the notion of a `linear' variety of semigroups.

Generalized Quasilinearization for Quasilinear Parabolic Equations with Nonlinearities of DC Type

Journal of Optimization Theory and Applications, 2001
The authors consider an initial-boundary value problem for a class of quasilinear parabolic equations whose lower-order nonlinearity is of d.c. function type (difference of two convex functions) with respect to the dependent variable. Combining the method of quasilinearization with the well-known method of upper and lower solutions together with the ...

Formant tracking with quasilinearization

ICASSP-88., International Conference on Acoustics, Speech, and Signal Processing, 1988
An algorithm for the calculation of formant tracks from a speech signal is presented. It is based on the method of quasilinearization, a nonlinear parameter estimation procedure. What distinguishes this method from the most other methods is the fact that the formants are directly calculated from the speech signal, using a nonlinear model for the speech
