摘要：
The appearance of divergence creates computational issues in the process of calculating the one-loop effective action of lambda phi(3) in quantum field theory. In this paper, it is demonstrated that using Krein space quantization with Ford's method of fluctuated metrics, divergence can be removed and that without using any traditional regularization method, it is possible to arrive at a finite solution for the effective action.
