Пересечение адельных групп на поверхности

Математический сборник. 2013. Т. 204. № 12. С. 3-14.
Будылин Р. Я., Горчинский С. О.

We solve a technical problem related to adeles on an algebraic surface. Given a finite set of natural numbers up to two, one associates an adelic group. We show that this operation commutes with taking intersections if the surface is defined over an uncountable field and we provide a counterexample otherwise.
