E. V. Shul'man Vologda State University
Abstract:
Several results on stability in spirit of Ulam and Hyers are obtained for classes of maps from groups to lattices satisfying the subadditivity condition
$$
F(gh) \subset F(g)\cup F(h) \quad \text{for all }\ g,h \in G.
$$
Keywords:
subadditive set-valued maps on groups, addition theorems, stability problems.
