When a unital F-algebra has all maximal left (right) ideals closed?
W. Żelazko (2006)
Studia Mathematica
Similarity:
We prove that a real or complex unital F-algebra has all maximal left ideals closed if and only if the set of all its invertible elements is open. Consequently, such an algebra also automatically has all maximal right ideals closed.
Combinatorics of ideals --- selectivity versus density
A. Kwela, P. Zakrzewski (2017)
Commentationes Mathematicae Universitatis Carolinae
Similarity:
This note is devoted to combinatorial properties of ideals on the set of natural numbers. By a result of Mathias, two such properties, selectivity and density, in the case of definable ideals, exclude each other. The purpose of this note is to measure the ``distance'' between them with the help of ultrafilter topologies of Louveau.

Łojasiewicz ideals in Denjoy-Carleman classes
Vincent Thilliez (2013)
Studia Mathematica
Similarity:
The classical notion of Łojasiewicz ideals of smooth functions is studied in the context of non-quasianalytic Denjoy-Carleman classes. In the case of principal ideals, we obtain a characterization of Łojasiewicz ideals in terms of properties of a generator. This characterization involves a certain type of estimates that differ from the usual Łojasiewicz inequality. We then show that basic properties of Łojasiewicz ideals in the case have a Denjoy-Carleman counterpart.
