This collection of Heinz König's publications connects to his book of
1997 "Measure and Integration" and presents significant developments in
the subject from then up to the present day. The result is a consistent
new version of measure theory, including selected applications. The
basic step is the introduction of the inner - (bullet) and outer -
(bullet) premeasures and their extension to unique maximal measures. New
"envelopes" for the initial set function (to replace the traditional
Carathéodory outer measures) have been created, which lead to much
simpler and more explicit treatment. In view of these new concepts, the
main results are unmatched in scope and plainness, as well as in
explicitness. Important examples are the formation of products, a
unified Daniell-Stone-Riesz representation theorem, and projective
limits.
Further to the contributions in this volume, after 2011 Heinz König
published two more articles that round up his work: On the marginals of
probability contents on lattices (Mathematika 58, No. 2, 319-323,
2012), and Measure and integration: the basic extension and
representation theorems in terms of new inner and outer envelopes
(Indag. Math., New Ser. 25, No. 2, 305-314, 2014).
