The Snapshot Problem for the Euler-Poisson-Darboux Equation

Fulton Gonzalez, Jue Wang, Jens Christensen +1

The generalized Euler-Poisson-Darboux (EPD) equation with complex parameter $α$ is given by $$ Δ_x u=\frac{\partial^2 u}{\partial t^2}+\frac{n-1+2α}{t}\,\frac{\partial u}{\partial…

The Snapshot Problem for the Wave equation

Fulton Gonzalez, Tomoyuki Kakehi, Jens Christensen +1

By definition, a wave is a $C^{\infty}$ solution $u (x, t)$ of the wave equation on $R^{n}$ , and a snapshot of the wave $u$ at time $t$ is the function $u_{t}$ on $R^{n}$ giv…
