Abstract: The structure of divergences in several nonpolynomial scalar quantum field theories are investigated. Various $n$-point Green functions for nonpolynomial theories are calculated and their renormalization is analyzed, with special regard for the nonpolynomial $\left|ϕ\right|^{3}$ theory in $4$ spacetime dimensions.
