摘要
得到了函数系M(Λ)在C[e-p(z)]中完备的一个充分条件,其中C[e-p(z)]是所有在复平面的某个无界集合L上连续,且当z趋向无穷时,f(z)exp(-p(z))趋向零的复函数f组成的集合.在一致范数‖f‖=supz∈le-p(z)|f(z)|下,C[e-p(z)]是一个Banach空间.
Obtain a sufficient condition for the completeness of the system M(A) in C[e^-p(z)] ,where C[e^-p(z)] isa weighted Banach space of complex continuous functions f on some infinite set L on complex plane,with f(z)exp (-p(z) ) vanishing at infinity, in the uniform norm ||f||=supe-p(z)z∈l|f(z)| with respect to the weight p(z).
