A New Extrapolation Economy Cascadic Multigrid Method for Image Restoration Problems
Zhaoteng Chu, Ziqi Yan, Chenliang Li
In this paper, a new extrapolation economy cascadic multigrid method is proposed to solve the image restoration model. The new method combines the new extrapolation formula and qua…

Anisotropic Compactification of Nonrelativistic M-Theory
Stephen Ebert, Ziqi Yan
We study a decoupling limit of M-theory where the three-form gauge potential becomes critical. This limit leads to nonrelativistic M-theory coupled to a non-Lorentzian spacetime ge…

Non-Lorentzian IIB Supergravity from a Polynomial Realization of SL(2,R)
Eric Bergshoeff, Kevin T. Grosvenor, Johannes Lahnsteiner +2
We derive the action and symmetries of the bosonic sector of non-Lorentzian IIB supergravity by taking the non-relativistic string limit. We find that the bosonic field content is…
