Gaussian beam interactions and inverse source problems for nonlinear wave equations

Matti Lassas, Tony Liimatainen, Valter Pohjola +1

We study the inverse source problem for the semilinear wave equation \[ (\Box_g + q_1)u + q_2 u^2 = F, \] on a globally hyperbolic Lorentzian manifold. We demonstrate that the coef…
