报告摘要：This article studies the birth of canard cycle and maximal canard in a piecewise smooth system with a fold–cusp singularity via regularization and blow-up technique. By introducing two scales in the regions respectively near and outside the switch manifold, a slow-fast framework in the setting of piecewise smooth systems is set up. By blowing up the degenerate objects, the process of canard explosion in piecewise smooth system with a fold–cusp singularity can be revealed.
