On the existence of nonoscillatory phase functions for second order differential equations in the high-frequency regime
Jhu Heitman, James Bremer, Vladimir Rokhlin
We observe that solutions of a large class of highly oscillatory second order linear ordinary differential equations can be approximated using nonoscillatory phase functions. In ad…

On the numerical solution of second order differential equations in the high-frequency regime
James Bremer
We describe an algorithm for the numerical solution of second order linear differential equations in the highly-oscillatory regime. It is founded on the recent observation that the…

On the asymptotics of Bessel functions in the Fresnel regime
Jhu Heitman, James Bremer, Vladimir Rokhlin +1
We introduce a version of the asymptotic expansions for Bessel functions , that is valid whenever (which is deep in the Fresnel regime), as opposed to th…
