Lambert summation method
A method for summing series of numbers. The series
is summable by Lambert's method to the number if
and if the series on the right-hand side converges. The method was proposed by J.H. Lambert . The summability of a series by the Cesàro summation method for some (cf. Cesàro summation methods) to the sum implies its summability by the Lambert method to the same sum, and if the series is summable by the Lambert method to the sum , then it is also summable by the Abel summation method to the same sum. Lambert's summation method is regular (see Regular summation methods).
