Analytical description of the dynamical moduli for a lognormal distribution of relaxation or retardation times
Some mathematical properties of the normalized dimensionless functions, involved in the expressions for the components of the dynamic moduli, for a lognormal distribution of retardation or relaxation times, are presented. Finally, it is shown how the mathematical properties can be used to obtain the...
