i got a degree on Physics and have several ideas on my own , unfortunately i do not have a physics sponsor :) in order to get an investigation grant :)

comment Nonlinear Klein Gordon equation
i understand this thanks :D but from this how could i reach to the final equation $$ (\Pi_{k} )_{t}+divJ =0 $$

comment Divergent Series
there is also zeta regularization however they say that zeta regularization of divergent series $ 1+2^{k}+3^{k}+.. $ breaks GAUGE INVARIANCE although i am not sure.

comment What is the relation between renormalization in physics and divergent series in mathematics?
i think DIMENSIONAL REGULARIZATION is hidding the power of zeta function because physicist prefer dimensional regularization over zeta function regularization for divergent integrals

comment can we PHYSCALLY (not by mathematics) justify that $ \zeta (-s)= 1+2^{s}+3^{s}+4^{s}+… $
but could we rely only in experimental prediction to conclude that every divergent zeta regularizable series in physics satisfies $ \zeta ((-m)= \sum_{n=1}^{\infty}n^{m} $
