"A Hadamard factorization of the Riemann Xi-function is constructed to characterize the zeros of the zeta function."
Like, dude, you are claiming to solve a Millennium problem, you're gonna have to put a little more effort into explaining, ya know, the breakthrough...
We care about the Riemann Hypothesis not for the theorem itself, but because the methods used to solve it will surely be revolutionary and it's those methods that are important, not the theorem.
That's what makes it a Millennium problem. So a paper like this immediately shows the author doesn't even understand why the problem is important, let alone its solution.
