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 Power divergences from loops
what happens with other logarithmic divergences such us $$ \int_{0}^{\infty} d^{4}p \frac{log^{n}(p/a)}{p+a} $$ or similars ?

comment is the renormalization unique?
also i was asking if within zeta regularization the identity $ \int_{0}^{\infty}dx = 1+1+1+1+1+1+...= \sum_{n=1}^{\infty}1=1/2 $

comment is the renormalization unique?
i am only asking if when you renormalize a UV divergence the renormalization method does not depend on the theory

comment change of variable in a 2-loop integral
we could use numerical method to int4egrate over the angles so we have only a integral over the radius of the 8-sphere 'r' can't not we do that ?

comment change of variable in a 2-loop integral
i was thinking about zeta or dimensional regularization, the integral over the angles could be made by numerical methods :D so we only should care about (perhaps) the integral over 'r'
