Conditions for global minimum in the $$A_4$$ symmetric 3HDM
نویسندگان
چکیده
There has been a great interest in three Higgs doublet models (3HDM) symmetric under an exact A4 symmetry. We provide the complete analytic necessary and sufficient conditions for point to be global minimum along neutral directions such models, discussing many of subtleties involved. also present number numerical examples, highlight those issues. then turn which break electric charge, presenting safe analytical condition bounded from below (BFB) potentials. Based on extensive simulations, we discuss one conjecture BFB charge breaking directions.

Some Conditions for Characterizing Minimum Face in Non-Radial DEA Models with Undesirable Outputs
The problem of utilizing undesirable (bad) outputs in DEA models often need replacing the assumption of free disposability of outputs by weak disposability of outputs. The Kuosmanen technology is the only correct representation of the fully convex technology exhibiting weak disposability of bad and good outputs. Also, there are some specific features of non-radial data envelopment analysis (DEA...
