Existence and upper semicontinuity of pullback attractors for Kirchhoff wave equations in time-dependent spaces

Kavli Affiliate: Ke Wang | First 5 Authors: Bin Yang, Yuming Qin, Alain Miranville, Ke Wang, | Summary: In this paper, we shall investigate the existence and upper semicontinuity of pullback attractors for non-autonomous Kirchhoff wave equations with a strong damping in the time-dependent space $X_t$. After deriving the existence and uniqueness of solutions by […]

Numerical Challenges in Modeling Gravothermal Collapse in Self-Interacting Dark Matter Halos

Igor Palubski, Oren Slone, Manoj Kaplinghat, Mariangela Lisanti, Fangzhou Jiang | Summary: [[{“value”:”When dark matter has a large cross section for self scattering, halos can undergo a process known as gravothermal core collapse, where the inner core rapidly increases in density and temperature. To date, several methods have been used to implement Self-Interacting Dark Matter~(SIDM) […]
