    • Classification of the Lie and Noether point symmetries for the Wave and the Klein–Gordon equations in pp-wave spacetimes 

      Paliathanasis A.; Tsamparlis M.; Mustafa M.T. ( Elsevier B.V. , 2018 , Article)
      A complete classification of the Lie and Noether point symmetries for the Klein–Gordon and the wave equation in pp-wave spacetimes is obtained. The classification analysis is carried out by reducing the problem of the ...

    • Quantization of the Szekeres system 

      Paliathanasis A.; Zampeli A.; Christodoulakis T.; Mustafa M.T. ( Institute of Physics Publishing , 2018 , Article)
      We study the quantum corrections on the Szekeres system in the context of canonical quantization in the presence of symmetries. We start from an effective point-like Lagrangian with two integrals of motion, one corresponding ...
