RT Journal Article T1 On dense-lineability of sets of functions on R A1 Aron, R.M. A1 García-Pacheco, F.J. A1 Pérez García, David A1 Seoane Sepúlveda, Juan Benigno AB A subset M of a topological vector space X is said to be dense-lineable in X if there exists an infinite dimensional linear manifold in M boolean OR {0} and dense in X. We give sufficient conditions for a lineable set to be dense-lineable, and we apply them to prove the dense-lineability of several subsets of e[a, b]. We also develop some techniques to show that the set of differentiable nowhere monotone functions is dense-lineable in e[a, b]. Other results related to density and dense-lineability of sets in Banach spaces are also presented.
