RT Journal Article T1 Q-linear functions, functions with dense graph, and everywhere surjectivity A1 GarcĂ­a-Pacheco, F.J. A1 Rambla-Barreno, F. A1 Seoane SepĂșlveda, Juan Benigno AB Let L, S and D denote, respectively, the set of Q-linear functions, the set of everywhere surjective functions and the set of dense-graph functions on R. In this note, we show that the sets D \ (S boolean OR L), S \ L, S boolean AND L and D boolean AND L \ S are lineable. Moreover, all these sets contain (omitting zero) a vector space of the biggest possible dimension, 2(c).
