Abstract: (Elsevier)
The effective potential is a useful and much-studied object. It is known to be both real and convex, but a perturbative calculation often gives a complex and nonconvex result. In this letter we address the apparent conflict between perturbation theory and the convexity of the effective potential.- field theory: scalar
- FIELD THEORY: PATH INTEGRAL
- FIELD THEORY: FINITE TEMPERATURE
- FIELD THEORY: EUCLIDEAN
- APPROXIMATION: EFFECTIVE POTENTIAL
- N-POINT FUNCTION
