Lie Group Symmetries as Integral Transforms of Fundamental Solutions [PDF]
We obtain fundamental solutions for PDEs of the form ut = x uxx +f(x)ux ??xru by showing that if the symmetry group of the PDE is nontrivial, it contains a standard integral transform of the fundamental solution. We show that in this case, the problem of

This is the first part of a series of papers dealing with eigenfunction expansions for the Schrödinger operator \(H=H_ 0+V(x)\), \(H_ 0=- \Delta /2\), where we assume V(x)\(\in {\mathcal B}^{\infty}(R^ n)\) is real-valued, \({\mathcal B}^{\infty}(R^ n)\) denoting the space of smooth functions on \(R^ n\) with bounded derivatives. In this part, we first

On the Fundamental Solutions to Stokes Equations
The author studies the behaviour of solutions to the stationary Stokes equations which have an isolated singularity. By using the power series expansions of harmonic and biharmonic functions one can describe the precise structure of solutions near singular points.

Fundamental solutions of two multidimensional elliptic equations
We construct fundamental solutions for two-multidimensional elliptic equations. The solutions are written in explicit form via hypergeometric Gauss functions for $\lambda=0$ and via confluent Horn functions for $\lambda\neq 0$. It is proved that the
