Nash-Moser techniques for nonlinear boundary-value problems

Electronic Journal of Differential Equations, 2003
A new linearization method is introduced for smooth short-time solvability of initial boundary value problems for nonlinear evolution equations. The technique based on an inverse function theorem of Nash-Moser type is illustrated by an application in the

Meshfree approach on buckling and free vibration analysis of porous FGM plate with proposed IHHSDT resting on the foundation

Curved and Layered Structures, 2019
In the present work, new inverse hyperbolic higher-order shear deformation theory (IHHSDT) is proposed and implemented for buckling analysis and free vibration analysis of porous Functionally Graded Material (FGM) plate on the foundation.

Comparative analysis on single- and multi-walled carbon nanotubes suspended for enhanced thermal energy transfer past stretching surfaces

AIP Advances
Flat and parabolic trough solar collectors concentrate sunlight onto a receiver tube containing the heat transfer liquid. Particularly, CNT nanofluids enhance the efficacy of energy harvesting in these systems.

Initial Buckling Behavior of Elastically Supported Rectangular FGM Plate based on Higher Order Shear Deformation Theory via Spline RBF Method [PDF]

Mechanics of Advanced Composite Structures
In the present paper, the effect of aspect ratio on the initial buckling response of an elastically supported rectangular FGM plate, the thin plate spline radial basis function (RBF) method can be used. This method involves the use of a thin plate spline

Local solvability of higher order semilinear parabolic equations

Hokkaido Mathematical Journal, 1992
In this paper is considered the parabolic equation \(u_ t = - Pu + f(t,x,d^ mu)\) in \(D^ T\) with initial-boundary conditions \(u(0,x) = u_ 0 (x)\) in \(G\) \(B_ 0u = B_ 1u = \cdots = B_{m - 1} u = 0\) on \(\partial G\), where \(Pu = \sum_{| \alpha |, | \beta | \leq m} ( - 1)^{| \beta |} D^ \beta (a_{\alpha, \beta} (x)D^ \alpha u)\), \(m > 1\), \(G ...
