RT Journal Article T1 On special partitions of [0, 1] and lineability within families bounded variation functions A1 Bernal González, L. A1 Fernández Sánchez, j: A1 Seoane Sepúlveda, Juan Benigno A1 Trutschnig, W. AB We show that there exists large algebraic structures (vector spaces, algebras, closed subspaces, etc.) formed entirely (except for 0), on one hand, by singular, nowhere monotonic functions on [0, 1] and, on the other hand, by absolutely continuous nowhere monotonic functions. Several tools, of independent interest, related to obtaining special partitions of R into uncountable collections will be provided and used. The results obtained in this note are either new or improved version of already existing ones.
