Learning based numerical methods for Helmholtz equation with high frequency
Yu Chen, Jin Cheng, Tingyue Li +1
High-frequency issues have been remarkably challenges in numerical methods for partial differential equations. In this paper, a learning based numerical method (LbNM) is proposed f…
Harmonic Measures and Numerical Computation of Cauchy Problems for Laplace Equations
Yu Chen, Jin Cheng, Shuai Lu +1
It is well known that Cauchy problem for Laplace equations is an ill-posed problem in Hadamard's sense. Small deviations in Cauchy data may lead to large errors in the solutions. I…
The Reconstruction and Prediction Algorithm of the Fractional TDD for the Local Outbreak of COVID-19
Yu Chen, Jin Cheng, Xiaoying Jiang +1
From late December, 2019, the novel Corona-Virus began to spread in the mainland of China. For predicting the trend of the Corona Virus spread, several time delay dynamic systems (…
A Time Delay Dynamical Model for Outbreak of 2019-nCoV and the Parameter Identification
Yu Chen, Jin Cheng, Yu Jiang +1
In this paper, we propose a novel dynamical system with time delay to describe the outbreak of 2019-nCoV in China. One typical feature of this epidemic is that it can spread in lat…
A Time Delay Dynamic System with External Source for the Local Outbreak of 2019-nCoV
Yu Chen, Jin Cheng, Yu Jiang +1
How to model the 2019 CoronaVirus (2019-nCov) spread in China is one of the most urgent and interesting problems in applied mathematics. In this paper, we propose a novel time dela…
Numerical Method for Parameter Inference of Nonlinear ODEs with Partial Observations
Yu Chen, Jin Cheng, Arvind Gupta +2
Parameter inference of dynamical systems is a challenging task faced by many researchers and practitioners across various fields. In many applications, it is common that only limit…
