Higgs Particles at Linear e+e- Colliders: theoretical issues

Abstract

I summarize the prospects for discovering and studying the properties of Higgs particles at future high-energy and high-luminosity $e^{+}{e}^{-}$ linear colliders. I will focus on the Higgs particle of the Standard Model and the Higgs bosons predicted by Supersymmetric theories.
