非代数quadrature域

Non-algebraic quadrature domains

Alexandre Eremenko, Erik Lundberg

摘要:

众所周知,在平面上,任何正交域(在经典意义上)的边界与多项式的零点集重合。我们表明,通过明确构建一些四维的例子,这并不总是如此。这证实了第二作者在维度4上的一个猜想。我们的方法是基于Schwarz势和涉及椭圆积分的第三类。

英文摘要:

It is well known that, in the plane, the boundary of any quadrature domain (in the classical sense) coincides with the zero set of a polynomial. We show, by explicitly constructing some four-dimensional examples, that this is not always the case. This confirms, in dimension 4, a conjecture of the second author. Our method is based on the Schwarz potential and involves elliptic integrals of the third kind.
