Effective Potential for $\lambda {\varphi }^4$ Theory at Finite Temperature in $R\otimes S^{D-1}$ and $R\otimes H^{D-1}$

T. Hattori, M. Hayashi, T. Inagaki +1

We calculate the explicit expression of the effective potential in a $\lambda {\varphi }^4$ theory at finite temperature in a static universe for arbitrary spacetime dimensions (2\leq D < 5). To s…
