Abstract We study monotone and strictly Hurwitz numbers from a bosonic Fock space perspective. This yields to an interpretation in terms of tropical geometry involving local multiplicities given by Gromov-Witten invariants. Furthermore, this enables us prove that main result Cavalieri-Johnson-Markwig-Ranganathan is actually equivalent the Gromov-Witten/Hurwitz correspondence Okounkov-Pandharipa...

In this paper, which is a sequel to [12], we proceed with our study of covers and decomposition laws for geometries related generalized quadrangles. particular, obtain higher law all Kantor-Knuth quadrangles generalizes one the main results in [12]. second part set ovoids (with given parameter) fixed finite parabolic quadrangle, relate embeddings into This point view gives rise an answer questi...

‎we call a ring $r$ right generalized semiperfect if every simple right $r$-module is an epimorphic image of a flat right $r$-module with small kernel‎, ‎that is‎, ‎every simple right $r$-module has a flat $b$-cover‎. ‎we give some properties of such rings along with examples‎. ‎we introduce flat strong covers as flat covers which are also flat $b$-covers and give characterizations of $a$-perfe...
