Existence of Rotating Magnetic Stars
Juhi Jang, Walter A. Strauss, Yilun Wu
We consider a star as a compressible fluid subject to gravitational and magnetic forces. This leads to an Euler-Poisson system coupled to a magnetic field, which may be regarded as…
Small-data global existence of solutions for the Pitaevskii model of superfluidity
Juhi Jang, Pranava Chaitanya Jayanti, Igor Kukavica
We investigate a micro-scale model of superfluidity derived by Pitaevskii in 1959 to describe the interacting dynamics between the superfluid and normal fluid phases of Helium-4. T…
Nonradial stability of expanding Goldreich-Weber stars
Mahir Hadžić, Juhi Jang, King Ming Lam
Goldreich-Weber solutions constitute a finite-parameter of expanding and collapsing solutions to the mass-critical Euler-Poisson system. Two subclasses of this family correspond to…
Asymptotic stability and sharp decay rates to the linearly stratified Boussinesq equations in horizontally periodic strip domain
Juhi Jang, Junha Kim
We consider an initial boundary value problem of the multi-dimensional Boussinesq equations in the absence of thermal diffusion with velocity damping or velocity diffusion under th…
opPINN: Physics-Informed Neural Network with operator learning to approximate solutions to the Fokker-Planck-Landau equation
Jae Yong Lee, Juhi Jang, Hyung Ju Hwang
We propose a hybrid framework opPINN: physics-informed neural network (PINN) with operator learning for approximating the solution to the Fokker-Planck-Landau (FPL) equation. The o…
Lagrangian time-analyticity for the Euler equations in a Sobolev domain
Juhi Jang, Igor Kukavica, Linfeng Li
Assuming only Sobolev regularity of the domain, we prove time-analyticity of Lagrangian trajectories for solutions of the Euler equations.
