A sufficient condition for strong almost-periodicity of scalarly almost periodic representations of the group of real numbers
We prove the following theorem: If every separable subspace Y of a Banach space X has a separable weak sequential closure in Y **, then every scalarly almost periodic group acting in X is strongly almost periodic.

Доведено теорему про те, що якщо кожний сепарабельний підпростір Y банахового простору X має сепарабельне слабке секвенційие замикання в Y **, то кожна скалярно майже періодична група, що діє в X, є сильно майже періодичною.
