This paper will primarily be concerned with the question if similar result holds true in the class of functions taking values in Riesz algebra with the common notion of the absolute value of an element stemming from the order structure of.

However, we prove that the exponential functional equation 1 is stable in dremlin Ulam-Hyers sense; that is, for any given satisfying inequality 3 there exists an exponential function which approximates uniformly on in the sense that the set is bounded in. Fremlin – Semantic Scholar.

We say that a real linear spaceendowed with a fremlib orderis a Riesz space if exists for all and We define the absolute value of frmelin the formula.

If a function satisfies the inequality for allthen either for all or for all. A great deal of measure theory is concerned with maps from and to measurable sets. Let be a semigroup and let be given.

This requires the notion of volume or measure of a measurable set. Work during the last two decades in topological measure theory meashre shown that measures in a space which is The quasi-Radon measures of D.

Measure Theoryvol. LO] 5 Sep A Riesz space is called Archimedean if, for eachthe inequality holds whenever the set is bounded above.

For frempin recent results concerning stability of functional equations in vector lattices we refer the interested reader to [7—12]. The study of various transformations of measures is the leitmotiv of this volume.
