THESE lectures are more in the nature of comments on wave mechanics than a formal treatment. This is especially true of the first three sections, on waves and corpuscles, the uncertainty principle, ...

This work establishes the first asymptotic stability result for multi-wave patterns in damped wave equations with partially linearly degenerate flux. The authors prove that global solutions converge ...

Time-domain finite-difference (TDFD) method is the most dominant approach for seismic wavefield simulation. Due to the memory and computational cost of the computer, finite-difference (FD) simulations ...
