相互作用场论的连续张量网络的建设，这是相关的理解规范/重力对应时空的出现，我们推导出一个非微扰泛函微分方程的标量场理论中的波泛函从精确重整化群方程。我们使用微扰理论检查方程的有效性。我们计算了一阶微扰的波泛函，并验证了它满足方程。
Motivated by the construction of continuum tensor networks for interacting field theories, which are relevant in understanding the emergence of space-time in the gauge/gravity correspondence, we derive a non-perturbative functional differential equation for wave functionals in scalar field theories from the exact renormalization group equation. We check the validity of the equation using the perturbation theory. We calculate the wave functional up to the first-order perturbation and verify that it satisfies the equation.
