Description

.The functions: En(x) = ∫(1 to +∞) (e-xt/tn)dt; KJn(x) = 1/xn ∫ (0 to x) un K0(u) du; KIn(x) = ∫ (0 to Π/2) (sinn-1 Θe - x/sinΘdΘ et Smn(ν) ∫ (0 to Π/2) cosn φ KIm+1 (2ν cosφ)dφ have been calculated for all values of the variable and for a wide range of variation of the parameters, using methods which are described here.

Abstract (French)

Les fonctions: En(x) = ∫(1 to +∞) (e-xt/tn)dt; KJn(x) = 1/xn ∫ (0 to x) un K0(u) du; KIn(x) = ∫ (0 to Π/2) (sinn-1 Θe - x/sinΘdΘ et Smn(ν) ∫ (0 to Π/2) cosn φ KIm+1 (2ν cosφ)dφ ont pu etre calculees pour toute valeur de la variable et pour un large domaine de variation des parametres au moyen des methodes decrites ici.
