我们研究了平面上定义在点的邻域上并满足带系数的Beltrami方程的acl -同纯态的局部性质。我们利用极值长度技术、环域模、四边形模和螺旋弧曲线族模，给出了点上共形的几何充要条件。
We study the local behaviour of ACL-homeomorphisms in the plane, defined in a neighbourhood of a point and satisfying the Beltrami equation with coefficient We use extremal length techniques, modules of ring domains, of quadrilaterals and of families of curves that are arcs of spirals to provide geometric sufficient and necessary conditions for conformality at a point.
