Since the encyclopedia of mathematics does not have as a lemma Peano spaces, I tried a scholar.google search for "peano spaces", the term that was more significant than the rather broad terms "locally" and "connected/pathconnected", that bring only those standard exercises from topology lecture notes like "topologist's comb" and "topologist's sine".
That cited abstract is indeed from paper and reminded me of those happy times when Bourbaki topologists were paid by the NATO research founds and created new categorial definitions by tons per year.
The article is
Positively expansive open maps of Peano spaces K Hiraide - Topology and its Applications, 1990 - Elsevier
but I don't read such stuff, always remembering the warning from Reed/Simon:
Functional analysis (and operator algebra and group theory), the paradigma of quantum mathematical physics, is no frutful playground for topologists.
