A term limit is a legal restriction that limits the number of terms an officeholder may serve in a particular elected office. When term limits are found in presidential and semi-presidential systems they act as a method of curbing the potential for monopoly, where a leader effectively becomes "president for life". This is intended to protect a republic from becoming a de facto dictatorship. Sometimes, there is an absolute or lifetime limit on the number of terms an officeholder may serve; sometimes, the restrictions are merely on the number of consecutive terms they may serve.
Sorry I know this may seem banal but it's really bugging me. I'm making space scenes of made up solar systems in a 3d modelling program and I want to name one "a ~ transit".

Why does the standard model have a higgs boson quadratic and a cuartic term but it does not have a cubic term? is there any problem if it happens to have a cubic term?
Thanks!
I have a doubt regarding its proof. First we assume that solution is of the form x^n-then we solve the quadratic equation and get two values of x-x1 & x2. After that we say solution is of the form ax1^n+bx2^n contradicting our previous assumption that solution is of the form x^n
