Title: Blow-up and general decay of solutions for a nonlinear viscoelastic equation Authors: Wenying Chen (Chongqing Three Gorges Univ., Chongqing, China) Yangping Xiong (Zhejiang Normal Univ., Jinhua 321004, China) Abstract: In this article we investigate a nonlinear viscoelastic equation that admits blow-up and decay. First, we establish blow-up results for this equation, even for vanishing initial energy. Then, we show that the solutions decay under suitable conditions. Submitted November 19, 2012.
