Abstract
We obtain two explicit closed form representations of Chandrasekhar'sH-functionsH(z) characterising transfer of radiation in an active amplifying medium corresponding to the dispersion function
Their basic properties are derived and the values of theH-functionH(z, ω) whenY(x)=ω/2, are approximately computed for values of ω in the range (−10−12)–(−102) and for values ofzε[0, 1].
