After the identification of 5-10% of trans-unsaturated acids, mainly elaidic (trans-octadec-9-enoic) and vaccenic (trans-octadec-11-enoic), in ox fat (Swern, Knight & Eddy, 1952), it has been shown in this Laboratory (Hartman, Shorland & McDonald, 1954, 1955) that substantial amounts of these acids appear in the depot fats of other ruminants (3-5-11-2 %) and in certain marsupials (18-1-21-0 %),...

and Applied Analysis 3 moreover we summarize some properties of a Hartman-type function. Lemma 4 (see [8]). LetG : I×I → R be the function defined as follows: as 0 ≤ t < η, G (t, τ) = { { { { { { { { { {

In this paper we investigate Hartman functions on a topological group G. Recall that (ι, C) is a group compactification of G if C is a compact group, ι : G → C is a continuous group homomorphism and ι(G) ⊆ C is dense. A bounded function f : G 7→ C is a Hartman function if there exists a group compactification (ι, C) and F : C → C such that f = F ◦ ι and F is Riemann integrable, i.e. the set of ...
