Посилання:Partitions of groups and matroids into independent subsets / T. Banakh, I. Protasov // Algebra and Discrete Mathematics. — 2010. — Vol. 10, № 1. — С. 1–7. — Бібліогр.: 4 назв. — англ.
Can the set R∖{0} be covered by countably many linearly (algebraically) independent subsets over the field Q? We use a matroid approach to show that an answer is ``Yes'' under the Continuum Hypothesis, and ``No'' under its negation.
