摘要：

The quantities psi-(x, y), phi-(x, y) which denote the number of positive integers less-than-or-equal-to x without prime divisors > y, < y respectively as well as the concept of a set of multiples within IN together with many wellknown results on these have their counterpart in arithmetical semigroups.
