RT Journal Article T1 Projective Evolution of Plane Curves A1 Castrillón López, Marco A1 Valdés Morales, Antonio AB We show that projectively invariant evolution operators have unavoidable singularities. In particular,we see that there exists no non-singular projective evolution operator well-defined over straight lines nor conics.
