Abstract: In this talk, we consider random walk and various statistical-mechanical models (such as self-avoiding walk, oriented percolation and percolation) that are defined by the $\mathbb{Z}^d$-symmetric probability distribution $D$. Suppose that the function $D(x)$ decays as $|x|^{-d-\alpha}$ with $\alpha>0$, We show that, for random walk with $d>\min\{\alpha,2\}$ and for the other models with $d$ bigger than the model-dependent upper-critical dimension, the critical two-point function decays as $|x|^{\min\{\alpha,2\}-d}$. The talk is based on joint work in progress with Akira Sakai.
