On solitary waves for the Korteweg--de Vries equation on metric star graphs
Delio Mugnolo, Diego Noja, Christian Seifert
We study the Korteweg--de Vries equation on a metric star graph and investigate existence of solitary waves on the metric graph in terms of the coefficients of the equation on each…
