Improved a priori error estimates for a space-time finite element method for parabolic problems
Thi Thanh Mai Ta, Quang Huy Nguyen, Phi Hung Pham
In this paper, we employ a space-time finite element method to discretize the parabolic initial-boundary value problem and extend its error analysis with refined estimates on unstr…

Error analysis of the space-time interface-fitted finite element method for an inverse source problem for an advection-diffusion equation with moving subdomains
Thi Thanh Mai Ta, Quang Huy Nguyen, Dinh Nho Hào
A space-time interface-fitted approximation of an inverse source problem for the advection-diffusion equation with moving subdomains is investigated. The problem is reformulated as…
