How to enable SSL for a homepage hosted on S3

[2018/04/13]

As Google Chrome will mark all HTTP websites unsafe later this year, it is time to figure out how to enable SSL on my websites. I currently have 3 websites under active management:

All three of them are hosted through AWS, but the homepage is by far the easiest as it only involves S3 and no EC2 instances. So at first I decided to turn on SSL at the homepage, which I succeeded with.

A histogram of the path energies ‐ the original motivation for the work

Quenched Central Limit Theorem in a Corner Growth Setting

[2018/04/12]

We consider point-to-point directed paths in a random environment on the two-dimensional integer lattice. For a general independent environment under mild assumptions we show that the quenched energy of a typical path satisfies a central limit theorem as the mesh of the lattice goes to zero. Our proofs rely on concentration of measure techniques and some combinatorial bounds on families of paths.

q-Boson sign

A sign in Boston Logan airport commemorating deformed Bosons

This sign works equally well for both $q$-Bosons and $t$-Bosons, so the choice of parameter is up to the tourist.

Installing specific versions of biblatex and texlive for arxiv

[2017/12/21]

(An update on the previous post)

So, I had a problem - my TeX distribution is new and updated, but I need to submit a paper to the arXiv, and arXiv has a different version of TeX distribution (currently 2016). The main problem is biblatex, which creates an incompatible version of the bibliography .bbl file. For this, I need an appropriate version of the biblatex package.

Forward transition probabilities associated with the Yang-Baxter field

Yang-Baxter field for spin Hall-Littlewood symmetric functions

[2017/12/13]

Employing bijectivisation of summation identities, we introduce local stochastic moves based on the Yang-Baxter equation for . Combining these moves leads to a new object which we call the spin Hall-Littlewood Yang-Baxter field - a probability distribution on two-dimensional arrays of particle configurations on the discrete line. We identify joint distributions along down-right paths in the Yang-Baxter field with spin Hall-Littlewood processes, a generalization of Schur processes. We consider various degenerations of the Yang-Baxter field leading to new dynamic versions of the stochastic six vertex model and of the Asymmetric Simple Exclusion Process.
