Analytic functions in the unit disc sharing values in a sector

Hong-Yan Xu, Ting-Bin Cao (2012)

Annales Polonici Mathematici

Similarity:

We deal with the uniqueness of analytic functions in the unit disc sharing four distinct values and obtain two theorems improving a previous result given by Mao and Liu (2009).

Stable families of analytic sets

Pandelis Dodos (2003)

Colloquium Mathematicae

Similarity:

We give a different proof of the well-known fact that any uncountable family of analytic subsets of a Polish space with the point-finite intersection property must contain a subfamily whose union is not analytic. Our approach is based on the Kunen-Martin theorem.
