Anti-Ultralocality and Plateau Models of Inflation
Joshua Shterenberg, David Garfinkle, Anna I. Rosenzweig +2
Anti-ultralocality refers to the growth of spatial gradient terms relative to velocity terms in the coupled Einstein--scalar field equations. It is a characteristic feature of dece…

Fisher Forecast of Finite-Size Effects with Future Gravitational Wave Detectors
Joshua Shterenberg, Zihan Zhou
We use Fisher information theory to forecast the bounds on the finite-size effects of astrophysical compact objects with next-generation gravitational wave detectors, including the…

Parity of Polynomial Multiplier Sequences for the Chebyshev Basis
Andrzej Piotrowski, Joshua Shterenberg
We demonstrate that if and is not an even function, then is not a multiplier sequence for the basis of Chebyshev polynomials of th…
