RT Journal Article T1 Attractors for parabolic equations with nonlinear boundary conditions, critical exponents, and singular initial data A1 Rodríguez Bernal, Aníbal AB The title of the paper says it all. The author considers a reaction-diffusion equation with nonlinear boundary conditions on a bounded domain Ω⊂R N . The initial value u 0 is allowed to be a function in L r (Ω) , with 1
