%0 Journal Article %T Blowup for a time-oscillating nonlinear heat equation %A Th. Cazenave %A M. Escobedo and E. Zuazua %J ACTA MATHEMATICA UNIVERSITATIS COMENIANAE %D 2013 %I Acta Mathematica Universitatis Comenianae %X In this paper, we study a nonlinear heat equation with a periodic time-oscillating term in factor of the nonlinearity. In particular, we give examples showing how the behavior of the solution can drastically change according to both the frequency of the oscillating factor and the size of the initial value. %K Semilinear heat equation %K time-oscillating nonlinearity %K finite-time blowup %U http://www.emis.de/journals/AMUC/_vol-82/_no_1/_cazenave/cazenave.html
