My mathematically-oriented work generally explores discrete geometric and probabilistic themes in physics, computation, and communication. Jack of most trades, master of none.
I can be reached at s.huntsman.1#alumni#nyu#edu (make the obvious substitutions for #).

Research situation in the field of Information Geometry
I would think it's natural to have a parameter space given by a Lie group, as in, e.g. mathoverflow.net/questions/14729 |

Listing all Lattice Points in a Box
Take suitable rational approximations and use BKZ (or LLL), then generate points and test them until you are guaranteed to be outside the box. |

inequality with exponents
What is $\delta(v)$? Is it the set of vertices adjacent to $v$? |

How should a mathematician approach the physics literature concerning percolation?
@AlexandreEremenko--I spent a lot of time with physics and physicists. So I am willing to deal with their way of reasoning. (I wish that was a two way street!) |

Reading Cardy is the best piece of advice here. He also has a book on renormalization (amazon.com/…) that touches briefly on percolation. |

Why does $d^n \exp(-x-x^{-1})/(dx)^n$ only have $n$ positive real zeroes?
Perhaps this can be brute forced with Faà di Bruno... |

Stationary distribution for time-inhomogeneous Markov process
Consider a time-inhomogeneous Markov process $X_t$ on a finite state space. Let $Q(t)$ denote the generator, and let $P(s,t)$ denote the corresponding transition kernel, i.e. $P(s,t) = U^{-1}(s)U(t)$, where the Markov propagator is \begin{equation} U(t) := \mathcal{TO}^* \exp \int_0^t Q(s) \ ds, \end{equation} and $\mathcal{TO}^*$ indicates the formal adjoint or reverse time-ordering operator. Now an initial distribution $\pi(0)$ is propagated as $\pi(t) = \pi(0)U(t)$. (See, e.g., Kleinrock, L. Queueing Systems, vol. 1. Wiley (1975).) |

Smooth bivariate functions identifiable under permutations
For $f$ symmetric and otherwise nice you may want to consider it as a graphon, cf. people.math.osu.edu/glasscock.4/graphons.pdf |

Regular epimorphisms in the category of simple undirected graphs
@DominicvanderZypen -- It doesn't answer the question: it merely reinforces Todd's comment and gives context along those lines. |
