Blow-up for a semilinear Tricomi equation in the oscillatory regime at the critical Strauss-type exponent

Diego Marcon, Wanderley Nunes do Nascimento, Matheus C. Santos

We study finite-time blow-up for a semilinear shifted Tricomi equation with decreasing propagation speed and an oscillatory scale-invariant mass. We focus on the Strauss-type criti…
