Enumeration and Decidable Properties of Automatic Sequences [PDF]
We show that various aspects of k-automatic sequences -- such as having an unbordered factor of length n -- are both decidable and effectively enumerable. As a consequence it follows that many related sequences are either k-automatic or k-regular.

Bounded Coordinate-Descent for Biological Sequence Classification in High Dimensional Predictor Space [PDF]
We present a framework for discriminative sequence classification where the learner works directly in the high dimensional predictor space of all subsequences in the training set.

Multitriangulations, pseudotriangulations and primitive sorting networks [PDF]
We study the set of all pseudoline arrangements with contact points which cover a given support. We define a natural notion of flip between these arrangements and study the graph of these flips.

Decoding Sequence Classification Models for Acquiring New Biological Insights [PDF]
Classifying biological sequences is one of the most important tasks in computational biology. In the last decade, support vector machines (SVMs) in combination with sequence kernels have emerged as a de-facto standard.

Grothendieck's theorem on non-abelian H^2 and local-global principles
A theorem of Grothendieck asserts that over a perfect field k of cohomological dimension one, all non-abelian H^2-cohomology sets of algebraic groups are trivial.

The elementary obstruction and homogeneous spaces [PDF]
Let $k$ be a field of characteristic zero and ${\bar k}$ an algebraic closure of $k$. For a geometrically integral variety $X$ over $k$, we write ${\bar k}(X)$ for the function field of ${\bar X}=X\times_k{\bar k}$.

Spectral Analysis of Kernel and Neural Embeddings: Optimization and Generalization [PDF]
We extend the recent results of (Arora et al. 2019). by spectral analysis of the representations corresponding to the kernel and neural embeddings. They showed that in a simple single-layer network, the alignment of the labels to the eigenvectors of the ...

Extensions of algebraic groups with finite quotient and nonabelian 2-cohomology
For a finite smooth algebraic group $F$ over a field $k$ and a smooth algebraic group $\bar G$ over the separable closure of $k$, we define the notion of $F$-kernel in $\bar G$ and we associate to it a set of nonabelian 2-cohomology. We use this to study

Scaling Limit of Deeply Virtual Compton Scattering [PDF]
I outline a perturbative QCD approach to the analysis of the deeply virtual Compton scattering process $\gamma^* p \to \gamma p'$ in the limit of vanishing momentum transfer $t= (p' - p)^2$.

On the abelian complexity of generalized Thue-Morse sequences
In this paper, we study the abelian complexity $\rho_n^{ab}(\mathbf{t}^{(k)})$ of generalized Thue-Morse sequences $\mathbf{t}^{(k)}$. We obtain the exact value of $\rho_n^{ab}(\mathbf{t}^{(k)})$ for every integer $n\geq k$.
