Recently, several experiments on ${\mathrm{La}}_{2\ensuremath{-}x}{\mathrm{Sr}}_{x}\mathrm{Cu}{\mathrm{O}}_{4}$ (LSCO) challenged the Fermi liquid picture for overdoped cuprates and stimulated intensive debates. In this work, we study the magnetotransport phenomena in such systems based on the Fermi liquid assumption. The Hall coefficient ${R}_{H}$ and magnetoresistivity ${\ensuremath{\rho}}_{xx}$ are investigated near the Van Hove singularity (VHS) โฆ
