Controls on strath terrace formation and evolution: The lower Guadiana River, Pulo do Lobo, Portugal
Ortega Becerril, José Antonio ; Garzón Heydt, Guillermina ; Tejero López, Rosa | Elsevier | 2018-10-15The lower Guadiana River carves a wide canyon in the Variscan metamorphic rocks of the SW Iberian Peninsula and presents an exceptionally homogeneous and well-preserved case of a strath terrace (ST) some 40?km long and 400?m wide. The rocky surf[...]![]()

We consider the Cauchy problem ut = ?(u)xx + ?(u), (t, x) ? R+ × R, u(0, x) = u0(x), x ? R, when the increasing function ? satisfies that ?(0) = 0 and the equation may degenerate at u = 0 (in the case of ?? (0) = 0). We consider the case of u0 ?[...]![]()

In 1951 V. 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 p[...]![]()

In this short note we show that we must replace the notion of connectedness used in the second author's paper cited in the heading. In particular, we show that with the current notion of connectedness some statements are false.![]()
