dc.descriptionWe prove that any evolution equation admitting a potential symmetry can always be reduced to another evolution equation such that the potential symmetry in question maps into the group of its contact symmetries. Based on this fact is out group approach to classification of evolution equations possessing non-local symmetries. We present several examples of classifications of second-order evolution equations admitting potential symmetries.
