In this paper we will prove the existence of weak solutions to the Korteweg–de Vries initial value problem on the real line with initial data; moreover, we will study the problem of orbital and asymptotic stability of solitons for integers ; finally, we will also prove new a priori bound for solutions to the Korteweg–de Vries equation. The paper will utilise the Miura transformation to link the Korteweg–de Vries equation to the modified Korteweg–de Vries equation.
