 Dear Prffesior,
                I am a research-fellow at a physics institute of India,
 working on “Finite Temperature Field Theory”,and “QGP phenomenology”.
 I am trying to use Feyncalc for my calculations but facing some problems.
 Let me explain them.
                 At finite temperature the propagators and the vertices
 loses the simple Lorentz invariant structure and acquires an admixture
 of both spatial and temporal components. Therefore, to perform these
 calculations the programe should be able to recognige both the zeroth
 and spatial components of a four-vector and know should be able to do
 calculations with DiracGamma[0] and Diracgamma[i],i=1,2,3 explicitly.
                 Can such things be done with feynCalc? Plese let me know.
                                        Sincerly
         
                                              Purnendu
