On finding gravitational waves from anisotropies of the Cosmic Microwave Background
Yiran Wang
The integrated Sachs-Wolfe (ISW) effect describes how photons are gravitationally redshifted, producing anisotropies in the Cosmic Microwave Background. We study the inverse proble…
The distribution of negative eigenvalues of Schrödinger operators on asymptotically hyperbolic manifolds
Antônio Sá Barreto, Yiran Wang
We study the asymptotic behavior of the counting function of negative eigenvalues of Schrödinger operators with real valued potentials on asymptotically hyperbolic manifolds. We es…
Robustness of data-driven approaches in limited angle tomography
Yiran Wang, Yimin Zhong
The limited angle Radon transform is notoriously difficult to invert due to its ill-posedness. In this work, we give a mathematical explanation that data-driven approaches can stab…
An Extreme Learning Machine-Based Method for Computational PDEs in Higher Dimensions
Yiran Wang, Suchuan Dong
We present two effective methods for solving high-dimensional partial differential equations (PDE) based on randomized neural networks. Motivated by the universal approximation pro…
Physics-preserving IMPES based multiscale methods for immiscible two-phase flow in highly heterogeneous porous media
Yiran Wang, Eric Chung, Shuyu Sun
In this paper, we propose a physics-preserving multiscale method to solve an immiscible two-phase flow problem, which is modeled as a coupling system consisting of Darcy's law and…
Two-sample Testing on Latent Distance Graphs With Unknown Link Functions
Yiran Wang, Minh Tang, Soumendra Nath Lahiri
We propose a valid and consistent test for the hypothesis that two latent distance random graphs on the same vertex set have the same generating latent positions, up to some uniden…
On the Clustering of Compact Galaxy Pairs in Dark Matter Haloes
Yiran Wang, R. J. Brunner
We analyze the clustering of photometrically selected galaxy pairs by using the halo-occupation distribution (HOD) model. We measure the angular two-point auto-correlation function…
