Funnily enough the Example Page 1 is wrong. Rendering du^n as du^*, and then nu^n-1 as nw^*-1.

It is impressive but...it really feels like those are the details that really really matter.

Second page is even worse. Ends in repeated \cdots and doesn’t finish parsing page. Also it read number 73 as 3 I guess because the previous section number was 2.

The main issue with OCR of anything with math in it is always that it has to be not 99.99% but 100% correct. Which is probably not possible.
