我们证明了在一定的混合条件下,尺寸为l的立方体的川崎动力学的谱隙以1/L2的速率收缩。我们还证明了如果Dobrushin-Shlosman混合条件在标准立方体中成立,则标准立方体中Glauber动力学的对数Sobolev不等式在立方体的大小上是一致成立的。
We prove that the spectral gap of the Kawasaki dynamics shrink at the rate of 1/L2 for cubes of sizeL provided that some mixing conditions are satisfied. We also prove that the logarithmic Sobolev inequality for the Glauber dynamics in standard cubes holds uniformly in the size of the cube if the Dobrushin-Shlosman mixing condition holds for standard cubes.
