An adaptive spectral method for oscillatory second-order linear ODEs with frequency-independent cost
Fruzsina J. Agocs, Alex H. Barnett
We introduce an efficient numerical method for second order linear ODEs whose solution may vary between highly oscillatory and slowly changing over the solution interval. In oscill…
Quantum initial conditions for curved inflating universes
Mary I. Letey, Zakhar Shumaylov, Fruzsina J. Agocs +3
We discuss the challenges of motivating, constructing, and quantizing a canonically normalized inflationary perturbation in spatially curved universes. We show that this has histor…
Finite inflation in curved space
Lukas T. Hergt, Fruzsina J. Agocs, Will J. Handley +2
We investigate the effects of non-zero spatial curvature on cosmic inflation in the light of cosmic microwave background (CMB) anisotropy measurements from the Planck 2018 legacy r…
