摘要翻译:
我们考虑了所谓本质孤立行列式奇点(孤立行列式奇点的自然推广)上的1-形式,说明了如何定义它们的Poincar e-Hopf指数的类似物,并描述了这些指数与径向指数之间的关系。对于孤立行列式奇点,我们讨论了全纯1型同调指数的性质及其与Poincar e-Hopf指数的关系。

英文摘要:
  We consider 1-forms on, so called, essentially isolated determinantal singularities (a natural generalization of isolated ones), show how to define analogues of the Poincar\'e--Hopf index for them, and describe relations between these indices and the radial index. For isolated determinantal singularities, we discuss properties of the homological index of a holomorphic 1-form and its relation with the Poincar\'e--Hopf index.
