Abstract We calculate analytical Collections vacuum stability or bounded from below conditions for general scalar potentials of a few fields.After a brief review of copositivity, we show how to find positivity conditions for more complicated potentials.We discuss the vacuum stability conditions of the general potential of two real scalars, without and with the Higgs boson included in the potential.

As further examples, we give explicit vacuum stability conditions Hemorrhoid Relief for the two Higgs doublet model with no explicit CP breaking, and for the $$mathbb {Z}_{3}$$ Z3 scalar dark matter with an inert doublet and a complex singlet.We give a short overview of positivity conditions for tensors of quartic couplings via tensor eigenvalues.
