Uniqueness and a Priori Estimates
Under some conditions on f(u), we show that for small, the only solutions to the following elliptic equation u ? u + f(u) = 0 in ; u > 0 in ; @u @ = 0 on @ are constants, provided that R 3 is convex. The proof only uses integration by parts.
متن کاملSingular Thought and the Contingent A Priori
De re or singular thoughts are, intuitively, those essentially or constitutively about a particular object or objects; any thought about different objects would be a different thought. What would a philosophical articulation or thematization of their nature be like? In spite of extensive discussion of the issue sin ce it was brought to the attention of the philosophical cornmunity in the late f...
متن کاملA Priori Estimates for Fluid Interface Problems
We consider the regularity of an interface between two incompressible and inviscid fluids flows in the presence of surface tension. We obtain local in time estimates on the interface in H 3 2 k+1 and the velocity fields in H 3 2 . These estimates are obtained using geometric considerations which show that the Kelvin-Helmholtz instabilities are a consequence of a curvature calculation.
متن کاملA Priori Estimates in Several Complex Variables
Classically there are two points of view in the study of global existence problems in the theory of functions of a complex variable. One is to piece together local solutions (such as power series), always staying within the category of holomorphic functions. This method seems to have been initiated by Weierstrass; in the theory of several complex variables it has been implemented by the study o...
متن کاملA priori estimates for excitable models
The reaction-diffusion system of Fitzhugh Nagumo is considered. The initialboundary problems with Neumann and Dirichlet conditions are analyzed. By means of an equivalent semilinear integrodifferential equation which characterizes several dissipative models of viscoelasticity, biology, and superconductivity, some results on existence, uniqueness and a priori estimates are deduced both in the li...
