KAWASAKI FUNCTION IN APPROXIMATION: A PEDAGOGICAL COMMUNICATION IN THE CONTEXT OF CRITICAL PHENOMENA

Close to the critical point, transports coefficients are revised at one loop self-consistent calculation. In this pedagogical communication, we compare the full Kawasaki function, associated with the transport coefficient, with its approximated form both analytically and graphically. We conclude that the approximated function in the critical phenomena is a very good candidate for acceptance and which, due to its simplicity, is advantageous over and hence preferable in carrying out calculations.
