Algebras with representable representations [PDF]
AbstractJust like group actions are represented by group automorphisms, Lie algebra actions are represented by derivations: up to isomorphism, a split extension of a Lie algebra $B$ by a Lie algebra $X$ corresponds to a Lie algebra morphism $B\to {\mathit {Der}}(X)$ from $B$ to the Lie algebra ${\mathit {Der}}(X)$ of derivations on $X$. In this article,

A graph $G = (V,E)$ is representable if there exists a word $W$ over the alphabet $V$ such that letters $x$ and $y$ alternate in $W$ if and only if $(x,y)\in E$ for each $x\not=y$. If $W$ is $k$-uniform (each letter of $W$ occurs exactly $k$ times in it) then $G$ is called $k$-representable. We prove that a graph is representable if and only if it is $

Diffusion representations [PDF]
Diffusion Maps framework is a kernel based method for manifold learning and data analysis that defines diffusion similarities by imposing a Markovian process on the given dataset. Analysis by this process uncovers the intrinsic geometric structures in the data.

From Formulas to Functions through Geometry: A Path to Understanding Algebraic Computations
The teaching of algebra at the secondary school level has faced a great revolution during the last 50 years. While previously, it was focused on technicisms and pure syntactic rules, the most modern trends recommend using a functional approach to algebra

Representation and Self-representation
The article analyzes experiences in archaeology and ethnology museums in Brazil that promote collaborative actions with Indigenous peoples involving studies of collections, exhibitions, preventive conservation, and collection management policies. We reflect on how these practices supplant thoughts and practices of the past concerning Indigenous rights,
