English
If R is a topological semiring and M is a topological R-module with continuous scalar actions and addition, then tsze R M is a topological semiring.
Русский
Если R — топологическое полугруппа-набор, а M — топологический R-модуль с непрерывными скалярами и сложением, то tsze R M является топологическим полугруппой по умножению.
