A general method to generate parallel iterations for finding all zeros of polynomial simultaneously
《Chinese Science Bulletin》1997年第22期1849-1852,共4页Han, DF Wang, XH 
SINCE there are many difficulties in finding a single root of a polynomial, it becomes moreand more important for parallel iterations to determine all roots simultaneously. Among theproposed methods, the iterative fam...

Project with authors partially supported by a U.P.G.C. grant, Hong Kong, the Croucher Foundation and Tianyuan Foundation, the NPDF grant and Academia Sinica, respectively.
Let f denote a transcendental entire function. A complex value a is said to be aPicard value of f,iff f（z）-a has at most finitely many zeros.As a result of severalstudies （for instance, Refs. [1-5]） on the questio...

ON CRITERION OF ALL ZEROS OF TRANSCENDENTAL FUNCTION f_n(λ, e^(-λτ))=det(A+Be^(-λτ)-Iλ) ON LEFT HALF-PLANE
《Chinese Science Bulletin》1985年第12期1699-1700,共2页李小军 
In this letter, we consider the distribution of zeros of the transcendental function fn(λ, e-λγ=det (A1 + B1e-λγ - Iλ). We use the following notations: A(aij)n×m= A1 + B1, B(bij)n×n = -B1A1,
