The reconstruction of the Higgs potential in the Standard Model or
supersymmetric theories demands the measurement of the trilinear
Higgs couplings. These couplings affect the multiple production of
Higgs bosons at high energy colliders. We present a systematic
overview of the cross sections for the production of pairs of
(light) neutral Higgs bosons at the LHC. The analysis is carried out
for the Standard Model and its minimal supersymmetric extension.
