By OpenAlex counts of its recent articles, its largest topics are Homotopy and Cohomology in Algebraic Topology, Algebraic structures and combinatorial models and Advanced Topics in Algebra, together about 63.7% of its articles. Its main subfields are Geometry and Topology and Mathematical Physics. (generated from OpenAlex topic counts and CAS ranking data)
Homology, Homotopy and Applications is a refereed journal which publishes high-quality papers in the general area of homotopy theory and algebraic topology, as well as applications of the ideas and results in this area. This means applications in the broadest possible sense, i.e. applications to other parts of mathematics such as number theory and algebraic geometry, as well as to areas outside of mathematics, such as computer science, physics, and statistics. Homotopy theory is also intended to be interpreted broadly, including algebraic K-theory, model categories, homotopy theory of varieties, etc. We particularly encourage innovative papers which point the way toward new applications of the subject.
