一类双正交级数的共轭级数

THE CONJUGATE SERIES OF A KIND OF BIORTHOGONAL SERIES

研究了基于多项式｛Ｗｎ（Ｚ）｝和其伴随函数｛Ｈｎ（ｚ）｝的双正交级数的共轭级数．

Let Wn(z) be a polynomial,andThe ellipse z=ch(τ+iθ) (0≤θ≤2π),eτ=d is denote .The conjugate series is discussed. The asymptotic express of the deviation between the partial sums of series(A) and the corresponding conjugate function is given.
