Introduction

There is always a problem that has been bothering me: the articles downloaded from Arxiv always have unreadable names (e.g., 1210.2368v3).
Therefore, I would like to automatically rename the articles downloaded from arXiv and move them to a specified folder instead of the system's default download folder in an automated manner.

Tampermonkey

Search Tampermonkey in Microsoft Edge Extensions, and downloand it.
If you prefer Chrome or Firefox, you may also find it in their extensions stores.
Open tampermonkey and add a script as follows:

    },
    onerror: function(error) {
        console.error("API请求失败：", error);
        // 失败时使用arXiv ID下载
        const fileName = `${arxivId.replace(".", "_")}.pdf`;
        GM_download({ url: window.location.href, name: fileName });
    }
});

This script can rename the arxiv file.

Python script

Write a python script to move the file. Make sure you have install packages: flask, shutil, and os.

Hands-on operation

You have to run the python script and Tampermonkey at the same time, so that you can implement the functions described in the introduction. If the python script is named by your_script.py, create a run_script.bat file in the same direction:

1
2
@echo off
python %~dp0\your_script.py %*

Add run.bat to the PATH of your computer. Then, when you want to download papers from arXiv, open cmd and type run_script.

Here is some targets which I want to acomplish in recent research:

Orbifold Fundamental Group Of 2-Orbifold

Orbifold is a natural generalization of manifold. One can define orbifold fundamental group for an orbifold, as we do for a manifold.
Though it has been almost half a century since Thurston gave this conception, no one gives a total description of the fundamental groups for all 2-orbifolds.

I believe I can calculate it in recent days.

Hurewize Theorem for Orbifold Fundamental Group and Weighted Homology

The motivation for me to calculate the orbifold fundamental groups for all 2-orbifolds, is that I want to prove there exists Hurewize isomorphism between orbifold fundamental group and the weighted homology group.
There are many attempts to build a homology theory for orbifolds, which can reflect the information about singular points of orbifolds. Weight homology is one of them. Try to build some connections with classicial conceptions will show that weight homology is a suitable tool to study orbifolds.

Which Cohomology Element Can Be Realized as Euler Class of Some Vector Bundle

The KO-groups and cohomology groups of toric manifolds are clear. I want to figure out which cohomology element of cohomology element can be realized as Euler class.

Build A Class of Non-positive Curvature Spaces

I am not sure whether I can figure out this. But I think this is an interisting topic.
