Two Hypotheses on the Exponential Class in the Class Of O-subexponential Infinitely Divisible Distributions

Two hypotheses on the class L ( γ ) in the class OS ∩ ID are discussed. Two weak hypotheses on the class L ( γ ) in the class OS ∩ ID are proved. A necessary and sufficient condition in order that, for every t > 0 , the t -th convolution power of a distribution in the class OS ∩ ID belongs to the...

Description
Summary:Two hypotheses on the class L ( γ ) in the class OS ∩ ID are discussed. Two weak hypotheses on the class L ( γ ) in the class OS ∩ ID are proved. A necessary and sufficient condition in order that, for every t > 0 , the t -th convolution power of a distribution in the class OS ∩ ID belongs to the class L ( γ ) is given. Sufficient conditions are given for the validity of two hypotheses on the class L ( γ ) .
