Stein方法、热核与紧李群元素幂的迹

Stein's method, heat kernel, and traces of powers of elements of compact Lie groups

Jason Fulman

摘要:

结合Stein方法和热核技术,我们证明了U(n,C),USp(n,C)或SO(n,R)中元素的j次幂的迹存在带j/n阶误差项的正规极限.与以前的作品相比,这里j可能随着n而增长。该技术应证明是有用的拉普拉斯近似本征函数的值分布的研究。

英文摘要:

Combining Stein's method with heat kernel techniques, we show that the trace of the jth power of an element of U(n,C), USp(n,C) or SO(n,R) has a normal limit with error term of order j/n. In contrast to previous works, here j may be growing with n. The technique should prove useful in the study of the value distribution of approximate eigenfunctions of Laplacians.
