Open AccessGlobal Evolution of the U(1) Higgs Boson: Nonlinear Stability and Uniform Energy Bounds
Relying on the hyperboloidal foliation method, we establish the nonlinear stability of the ground state of the U(1) standard model of electroweak interactions. This amounts to establishing a global-in-time theory...

Stability of Quasilinear Waves in \(1+1\) Dimension Under Null Condition
We are interested in the global-in-time existence results for quasilinear wave equations satisfying null condition in one dimension. The main difficulty is that waves do not decay in one dimension space, and w...

Global solution to the 3D Dirac–Klein–Gordon system with uniform energy bounds
On the (1+3) dimensional Minkowski spacetime, for small, regular initial data, it is well-known that the Dirac–Klein–Gordon system admits a global solution. In the present paper, we aim to establish the unifor...
