Sharp bounds are given for the highest multiplicity of zeros of polynomials in terms of their norm on Jordan curves and arcs. The results extend a theorem of Erdős and Turán and solve a problem of them from 1940.

多项式零点的多重性
对于多项式零的最高多重性,按照其在约旦曲线和弧线上的范数给出了尖锐的界限。结果扩展了Erdős和Turán的一个定理,并从1940年开始解决它们的问题。
