Abstract
A life table is a positive decreasing function l ξ of ξ≥0 with l ∞=0, where of course l ∞ = limξ→∞ l ξ = 0. We imagine a closed group of persons with the same age, called lives, observed over time. Then l ξ is the number of persons alive at age ξ. This is a convenient interpretation (the construction of practical life tables is not based on it).
