Claimed proof of the ABC conjecture (Zha, 2009)

[R.D. Silverman]

The following article claims to prove the abc conjecture:

While the proof may be in error, it is not a crank effort.
The author (Zha) has his doctorate in Arithmetic Algebraic
Geometry and Algebraic Number Theory from U. of Chicago.

I am not an expert, but the approach seems plausible.

This may be a silly question, but, why is this only showing up here now?

I mean, the original arXiv submission is over 10 years old, and the most recent revision there is over 3 & 1/2 years old.

Have there been recent developments?

Only because of necroposting, of course.

The newest possible proof from Shinichi Mochizuki in 2012 for which he invented Inter-universal Teichmüller theory.

From what I read the proof is barely understood by any other mathematicians but a few claim to have found a big hole in the proof while others claim it is good.

I usually see updates on what's happening with the abc conjecture on Peter Woit's blog. He's done a pretty good job of keeping up with what's happening with Mochizuki's proof (and its, alleged, attendant problems).
