Retract this!

Martin Paul Eve · Front Matter · 2023

Today's big news is that Crossref has acquired the Retraction Watch database of expressions of concerns and retractions and has made it openly accessible to anyone who wants to use it. I'm waiting for full confirmation of the license or public domain dedication under which it will be released, but this is still a great commitment of Crossref to the POSI principles. The liberation of this database is good for science and scholarship in general.

I’m waiting for full confirmation of the license or public domain dedication under which it will be released, but this is still a great commitment of Crossref to the POSI principles.

Generalised retract semigroups

Karl Auinger · Bulletin of the Australian Mathematical Society · 1991

We give a description of the structure of the semigroups for which each principal ideal is a retract. The globally idempotent case is solved quickly using a—suitably modified—construction which has been developed by Tully for the study of semigroups in which each ideal is a retract. The general case can be treated by a naturally obtained semigroup of subsets of the semigroup constructed for the globally idempotent case.

Note on deformation retract

Kiyoshi Aoki · Proceedings of the Japan Academy Series A Mathematical Sciences · 1954

The main object of this note is to study a mapping which has a torus as the image space. The methods of the paper are strongly influenced by Spanier's proofs [5].

Retract extensions of lattices

Niovi Kehayopulu · Russian Mathematics · 2011

As a continuation of the paper on the ideal extensions of lattices considered in Russian Mathematics (Iz. VUZ) 53 (2), 41–57 (2009), we present here a detailed exposition of the retract extensions of lattices.
