Haruhisa ENOMOTO
I am Haruhisa Enomoto (榎本 悠久 in Japanese), a postdoc at
Graduate School of Science,
Osaka Metropolitan University in Japan.
an R&D Engineer at Acompany Co., Ltd. (privacy-tech startup) in Japan.
- My personal e-mail: dakenga [at] gmail.com, math-related e-mail are welcome!
IMPORTANT: I will leave math academia in March 2024 and join a company in April 2024. See here (Japanese) for more details if you are interested in why I decided to leave academia.
This site will available after March 2024, but I haven’t decided whether I will update this site or not, and its contents.
The e-mail address below will not be available after March 2024.
FD Applet - an applet for Finite-Dimentional algebras has been released!
Online version: https://fd-applet.dt.r.appspot.com/
Since April 2022, My e-mail address and affiliation has changed since the name of my university has changed.
New E-mail:

Update History
- 2023-11-13: I gave several talks and received the Hida award!
- 2023-06-13: I gave an introductory lectures of $\tau$-tilting and torsion classes using split projectives and wide intervals in Japanese.
- 2023-04-04: Add FD Applet!
- 2023-04-04: New theme!
- 2023-02-03: New preprint Maximal self-orthogonal modules and a new generalization of tilting modules, and add some related problems to Questions.
- 2022-11-22: I added a counter-example of a Questions about the lattice-theoretical characterization of the lattice of torsion classes, and add a small Program used to find it.
- 2022-09-10: AR quiver calculator is now (probably) supported on Mac!
- 2022-08-31: New preprint Image-extension-closed subcategories of module categories of hereditary algebras (with A. Sakai)!
- 2022-08-13: Major update on AR quiver calculator!. Now this can compute various subcats (torsion classes, wide subcats, ICE-closed,…) and their Ext-projectives from your AR quiver visually!
- 2022-08-08: New preprint Grothendieck monoids of extriangulated categories (with S. Saito)!
