What is the correct definition of semisimple linear category?
However, I have an issue with their (and by proxy, Müger's) approach. Namely, they require that the category has finite biproducts (direct sums). …

What is neutral constructive mathematics
You'll probably have better luck with the phrase "intuitionistic higher-order logic" (IHOL). A good place to start is the book by Lambek and Scott, Introduction to Higher Order Categorical Logic. But …

How to write math well?
Hmm, I'm about twelve years late to the party - anyway, since the post has just popped up at the front page, here's a list of suggestions that I try to follow when writing mathematics, mainly because …

Characterizing non-zero polynomials on semialgebraic sets: a kind of positivstellensatz gene...
One way out of this is to search among all polynomials of the form $q = \sigma_0 + \sum_i \sigma_i f_i$, and try to find a $q$ whose symmetric positive semidefinite Gram matrix is of rank one, a convex proxy …

How can we use Martingales to identify an unknown particle?
This gives $Y_N$ with subgaussian proxy $\Sigma_N = \sum_i \sigma_i^2$. Then we can guess positive charge if $Y_N > 1/2$ and negative if $Y_N \le 1/2$. … The subgaussian proxy says the guess is correct with probability $O(e^{-K \Sigma_n})$ for some fixed $K >0$.
So far so good. But what if we are instead interested in tail bounds for the guesses. …

Riemann Hypothesis and Euler product
Since the (absolute convergence of the) Euler product implies nonvanishing for $\sigma > 1$, it is possible that the Euler product is just a proxy for that nonvanishing. …

Inequality on the Hellinger distance between Poisson and mixture of Poisson
I have an indirect (but simple) proof, which relies on the chi-squared distance $\chi^2(p,q) = \sum_n \frac{(p(n)-q(n))^2}{q(n)}$ as a proxy, along with the fact that $H(p,q)^2 \leq 1\land \chi^2(p,q)$ …
