The stability of platicons in hot cavities with normal group velocity at the
interplay of Kerr and thermal nonlinearities was addressed numerically. The
stability analysis was performed for different ranges of pump amplitude,
thermal nonlinearity coefficient and thermal relaxation time. It was revealed
that for the positive thermal effect, the high-energy wide platicons are
stable, while the negative thermal coefficient provides the stability of narrow
platicons.Comment: 4 pages, 8 figure
