Continuous Cluster Expansion for Field Theories

A new version of the cluster expansion is proposed without breaking the translation and rotation invariance. As an application of this technique, we construct the connected Schwinger functions of the regularized $ϕ^4$ theory in a continuous way.

An inductive realization of Loop Vertex Expansion is proposed and is applied to the construction of the $ϕ_1^4$ theory. It appears simpler and more natural than the standard one at least for some situations.
