Research On The Actuarial Model Of The Contribution Rate Of The New Rural Social Pension Insurance With The Stochastic Interest Rate

G.Y.Ni and others study tensor analysis problems mmotivated by the geometric measure of entanglement,in the complex number field,G.Y.Ni and others defined the U-eigenvalue?the US-eigenvaluer and get the upper bound on the number of distinct US-eigenvalues of the complex symmetric tensor.In this paper,a general complex tensor is embedded into a complex symmetric tensor.We show the connection between the U-eigenvalue of a general complex tensor and the US-eigenvalue of a complex symmetric tensor,then we get the upper bound on the number of distinct U-eigenvalues of the general complex tensor.Finally,using the result of the best complex symmetric rank one approximation of complex symmetric tensors,we get the result on the best complex rank one approximation of a general complex tensor.Finally,for complex tensor,we would convert the computation of U-eigenvalues and US-eigenvalues to Z-eigenvalues.
