Abstract
The multiple point principle (MPP) is applied to the nonsupersymmetric two-Higgs doublet extension of the standard model (SM). The existence of a large set of degenerate vacua at some high energy scale caused by the MPP results in a few relations between Higgs self-coupling constants which can be examined at future colliders. The numerical analysis reveals that these MPP conditions constrain the mass of the SM-like Higgs boson to lie below 180 GeV for a wide set of MPP scales $\ensuremath{\Lambda}$ and $\mathrm{tan}\ensuremath{\beta}$.
