Query: Co-positivity of tensors and Stability conditions of two Higgs
  potentials   We give how to calculate the vacuum stability conditions of scalar potential
for two Higgs doublet model with explicit CP conservation. Moreover, the
analytical sufficient and necessary conditions are obtained. The argument
methods are first used to study the tensor with two parameters.
