Dear Mycola

What was the question?

Dear Dikeos Mario,

I just did not see an option for "Comment"

and put it as a question.

Anyway, it seems that contacts between the present versions of QFT

and statistical physics are interesting and useful, though nearly nothing

about this can be found in the literature.

For example, with the appropriate choice of g^2~\epsilon=4-d,

I have found a one-to one correspondence between a g-expansion for the pressure of the authors

of the present project at order g^3 and the Casimir amplitude in one of our papers

at order \epsilon^{3/2} of the \epsilon-expansion near the dimension d=4.

Best regards,

Mykola

Dear Mykola

Although I have to read carefully what these  people are doing I have the impression they

reinvent many wheels constructed in statistical physics before.They will eventually realize

that almost all relevant problems are many body problems.

Dear Dikeos Mario,

when people realize the similarity in solving problems of field theory and many-body systems,

they come to very nice developments.

Examples are

QFT, Renormalization Group -> Phase Transitions and Critical Phenomena

Lifshitz point theory -> Lorentz violating theory -> Horava gravity

The present authors contributed very much to resummations in QFT.

In this respect the analogous Condensed Matter problems are not developed to the same extent.

Regards,

Mykola

Dear  Mycola f

I think Abricosov  etall Ginzburg landau  and condensed matter  many bodqy problems

including critical fluctuations are more important than formal exercises in  QFT with all

its  singularities and  weak connections to  reality although they are better than the

cosmological bullshit of dark energies hidden matter parallel universes etc.

brainwashing people in   the media.

Dear Dikeos Mario,

the important point is that problems in such apparently different fields

are often described by the same mathematics.

Then, using outcomes of "formal exercises" in one field can lead to

beautiful developments in another area.

Mykola

Dear Mykola

I will download your papers read them and continue our converation later

Best regards
