Jarnik constructed two continuous functions whose Volterra convolution is nowhere differentiable. We generalize Jarnik's results by proving that the set of such functions is maximal lineable. This would shed some light on a question posed in 1973 on the structure of the set of continuous functions whose Volterra convolution is nowhere differentiable.engjournal articlehttp://www.sciencedirect.com/science/article/pii/S0022247X13010871http://www.sciencedirect.com/restricted access517LineabilitySpaceabilityAlgebrabilityConvolutionNowhere differentiable functionAnálisis matemático1202 Análisis y Análisis Funcional
