【摘要】 利用Fourier级数为工具,在L2(G)上构造了一个紧对称正定算子Kr,并利用正定的紧算子的迹和其迹范数一致的性质,证明了该算子是一个迹类算子,使之成为研究积分算子本征值分布的一个工具.更多还原

【Abstract】 By using the methods of Fourier series,A compact symmetrics positive definite operator K-r is definited in L~2(G) spaces,and by using the properties that the trace of compact positive definite operator agrees with its trace norm,we obtain that the operator of K-r is trace class operator.更多还原
