Small solutions of $x^2-a^3 y^2=\pm 1$

It is better to ask one question per post. Here is the answer to Q1. Assume that $(x,y)$ is a positive integer solution of $(1)$. Then $(x,ay)$ is a solution of $X^2-aY^2=1$. Let us restrict to $a=u^2-...

Consequences of Kirti Joshi's new preprint about p-adic Teichmüller theory on the validity of IUT and on the ABC conjecture

Since my preprint [Constr. IV] appeared on the arixv, I have received many questions about my work. I continue to answer these emails and I have collected many of the questions and answers in this Q&...

Global character of ABC/Szpiro inequalities

This is from my recent email to Peter Scholze in response to his post above: My response to Peter Scholze: I read your comments on MathOverFlow. Thank you for your kind words. Somehow, once again, we ...

Global character of ABC/Szpiro inequalities

Mochizuki's claim is right in spirit but not stated completely rigorously. I want to explain (1) what part is not completely rigorous and (2) why this is not problematic for the analysis of any ...

Global character of ABC/Szpiro inequalities

For concreteness, consider the $abc$-inequality with $\epsilon=1$, i.e. that there is some integer $K$ such that for all coprime integers $a,b,c$ with $a+b=c$, one has $$abc\leq K \prod_{p|abc} p^6.$$ ...

Global character of ABC/Szpiro inequalities

This is not an answer to the question but too long for a comment. It is interesting to ask if one can prove the ABC inequality just for the tuple $(1,p^n,1+p^n)$ directly for fixed $p$. ABC says $$\...

Consequences of Kirti Joshi's new preprint about p-adic Teichmüller theory on the validity of IUT and on the ABC conjecture

My response to Mochizuki's Comments on my papers [Preprints: Construction of Arith. Holo. Strs I, II, II(1/2), III, IV. I will restrict myself to mathematics. My work shows that Mochizuki's [IUT 1-3] ...
