Title: Using Lie symmetries in epidemiology 

Author: Maria Clara Nucci (Univ. di  Perugia, Italy)
 
Abstract: 
Lie symmetry method has been and still is successfully applied in
different problems of physics for about a hundred years, but its
application in  epidemiology has been rare perhaps because
the ordinary differential equations studied in this field are
generally of first-order in contrast with those in physics
which are usually of second-order.
Here we exemplify the use of Lie symmetry method  in the study of
mathematical models in epidemiology, and show how it complements
the  mathematical techniques (qualitative and numerical analysis)
traditionally used.
