Uma vez que tal equação possui estrutura variacional, determinamos quais são suas simetrias de Noether e a partir delas estabelecemos suas respectivas leis de conservação / Abstract: In this work, we carry out a complete group classification of Lie point symmetries of semilinear Kohn - Laplace equations on the three-dimensional Heisenberg group. Since this equation has variational structure, we determine which of its symmetries are Noether's symmetries. Then we establish their respectives conservation laws / Doutorado / Matematica Aplicada / Doutor em Matemática Aplicada
