NettetMain article: integrable systems PDEs that arise from integrable systems are often the easiest to study, and can sometimes be completely solved. A well-known example is the Korteweg–de Vries equation . Symmetry [ edit] Some systems of PDEs have large symmetry groups. NettetI have reasons to believe that the integral has logarithmic singularities, and can be expressed as: I(t) = f(t) + ∑ βj log(1 − t2 β2j) Where f(t) is an even,entire function … NettetAbstract.

NettetWe examine whether the Painleve property is necessary for the integrability of partial differential equations (PDEs). We show that in analogy to what happens in the case of ordinary differential equations (ODEs) there exists a class of PDEs, integrable through linearisation, which do not possess the Painleve property.
