T1 φ^4 theory in 1+d dimensions at high temperature: dimensional reductinon
A1 Fernández Álvarez-Estrada, Ramón
AB The φ^4 theory in 1+d dimensions is analyzed at high temperatures in the imaginary-time formalism. General results are given for the leading high-temperature contributions to all renormalized Careen's functions. The latter are generated by a high-temperature partition function which describes another φ^4 theory in d spatial dimensions with special mass renormalizations. The triviality/nontriviality of the (φ^4)_1+3 theory is discussed briefiy.
