Some Remarks on the Group of Isometries of a Metric Space,n result contained in Theorem 4.1 and Theorem 4.2 is that in case .≠2 all these groups are isomorphic and, consequently, they are independent of .. In the last section, the isometry dimension of a finite group with respect to a given metric on the space ℝ. is introduced.

Remarks on Stability of the Linear Functional Equation in Single Variable,ng a nonempty set . into a Banach space . over a field ., where . is a fixed positive integer and the functions .:.→., .:.→. and ., .=1,…,., are given. Those observations complement the results in our earlier paper (Brzdȩk et al. in J. Math. Anal. Appl. 373:680–689, .).

,Hyers–Ulam–Rassias Stability of Orthogonal Additive Mappings,ity originated from Th.M. Rassias’ stability theorem that appeared in his paper: On the stability of the linear mapping in Banach spaces, Proc. Am. Math. Soc. 72:297–300, .. Our results generalize and simplify the result of R. Ger and J. Sikorska (Bull. Pol. Acad. Sci., Math. 43(2):143–151, .). See
