Non-standard perturbative methods for the effective potential in λφ4 QFT
Description
The effective potential in scalar QFT is calculated in the non-standard perturbative methods and compared with the conventional loop expansion. In the space time dimensions 0 and 1 the results are compared with the ''exact'' effective potential obtained numerically. In 4 dimensions we show that λφ4 theory is non-interacting. (author)
