Abstract: We study theoretically the renormalization of the spin-orbit-coupling constant of two-dimensional electrons by electron-electron interactions. We demonstrate that, similarly to the g factor, the renormalization corresponds to the enhancement, although the magnitude of the enhancement is weaker than that for the g factor. For high-electron concentrations (small interaction parameter ${r}_{s})$ the enhancement factor is evaluated analytically within the static random phase approximation. For large ${r}_{s}\ensuremath{\sim}10,$ we use an approximate expression for effective electron-electron interaction, which takes into account the local field factor, and calculate the enhancement numerically. We also study the interplay between the interaction-enhanced Zeeman splitting and interaction-enhanced spin-orbit coupling.
