*n*-set of real numbers contains a triple whose sum is zero. We qualify such a triple of

*degenerate*because the probability of finding one in a random input is zero. We consider the 3POL problem, an algebraic generalization of 3SUM where we replace the sum function by a constant-degree polynomial in three variables. The motivations are threefold. Raz et al. gave an...

*F*independent on the camera positions, when its inputs are image point configurations that are perspective projections of the intersection of three quadrics in $$\mathbb {P}^3$$ P 3 . This generalizes a multiple results of the degeneracies of the 8-point algorithm. We give an algorithm that improves...

*Éléments de Géométrie Algébrique*(EGA) by A. Grothendieck and J. Dieudonné appeared, an encyclopedic work on the foundations of Grothendieck’s algebraic geometry. We sketch some of the most important concepts developed there, comparing it to the classical language, and mention a few results in algebraic and arithmetic geometry which have since been proved using the new framework.

*k*-mer frequency counts can be used to reconstruct phylogenies without first computing a sequence alignment. Past work has shown that effective use of

*k*-mer methods depends on (1) model-based corrections to distances based on

*k*-mers and (2) breaking long sequences into blocks to obtain repeated trials from the sequence-generating process. Good performance...
