      Extended conformal symmetries and U(1) currents 

      Bakas, Ioannis; Kakas, Antonis C. (1989)
      The authors investigate the structure of extended conformal algebras generated by local chiral fields of spin 1,2,. . .,n using the Gelfand-Dickey algebra of formal pseudodifferential operators for the gl(n) algebra. The ...

      Quantum mechanics of non-linear systems 

      Bakas, Ioannis; Kakas, Antonis C. (1987)
      A generalisation of Weyl's correspondence rule and the associated Moyal bracket for systems with non-linear phase spaces that admit symplectic transitive group actions is presented. This provides a simple account with ...

      Virasoro algebra anomalies and deformations 

      Bakas, Ioannis; Kakas, Antonis C. (1987)
      The authors relate the anomalies of string theories to the mathematical obstructions of Dirac's canonical quantisation. The cohomological features of the deformation approach to the quantisation procedure determine the ...
