Combinatorics: The Mathematics of Fair Thieves and Sophisticated Forgetters
Frontiers for Young Minds, 2023 Mathematics is the most logical and unbiased scientific field there is. What is true in mathematics today will forever stay true, and mathematical arguments will always clearly indicate which side “wins”. These are some of the characteristics of mathematics that I have liked very much since I was young.

Sections and projections of the outer and inner regularizations of a convex body
Mathematika, Volume 72, Issue 3, July 2026.Abstract We establish new geometric inequalities comparing the volumes of sections and projections of a convex body, whose barycenter or Santaló point is at the origin, with those of its inner and outer regularizations. We also provide functional extensions of these inequalities to the setting of log‐concave functions. Our approach relies on the recent

Properly Colored Cycles in Edge‐Colored Balanced Bipartite Graphs
Journal of Graph Theory, Volume 112, Issue 2, Page 37-53, June 2026.ABSTRACT Let G n , n c denote a (not necessarily properly) edge‐colored balanced bipartite graph on 2 n vertices, that is, in which every edge is assigned a color. A cycle C in G n , n c is called properly colored if any two consecutive edges of C have distinct colors.

Perspectives for proof unwinding by programming languages techniques [PDF]
, 2016 In this chapter, we propose some future directions of work, potentially beneficial to Mathematics and its foundations, based on the recent import of methodology from the theory of programming languages into proof theory.

On Regular Quaternary Hadamard Matrices
Journal of Combinatorial Designs, Volume 34, Issue 5, Page 215-227, May 2026.ABSTRACT Through the use of regularizing vectors, all regular quaternary Hadamard matrices of orders 10 and 18 have been successfully identified. Of these, two matrices of order 10 and 184 matrices of order 18 were found to have unbiased mates. Converting the quaternary Hadamard matrices of order 18 to real Hadamard matrices, the study uncovered that ...

New directions in enumerative chess problems [PDF]
, 2005 Normally a chess problem must have a unique solution, and is deemed unsound even if there are alternatives that differ only in the order in which the same moves are played.

, 2016 The science’s function is realizing the natural world, developing our society in coordination with natural laws and the mathematics provides the quantitative tool and method for solving problems helping with that understanding. Generally, understanding a natural thing by mathematical ways or means to other sciences are respectively establishing ...

In‐and‐Out: Algorithmic Diffusion for Sampling Convex Bodies
Random Structures &Algorithms, Volume 68, Issue 3, May 2026.ABSTRACT We present a new random walk for uniformly sampling high‐dimensional convex bodies. It achieves state‐of‐the‐art runtime complexity with stronger guarantees on the output than previously known, namely in Rényi divergence (which implies TV, 𝒲2, KL, χ2$$ {\chi}^2 $$).

Two‐Round Ramsey Games on Random Graphs
Random Structures &Algorithms, Volume 68, Issue 3, May 2026.ABSTRACT Motivated by the investigation of sharpness of thresholds for Ramsey properties in random graphs, Friedgut, Kohayakawa, Rödl, Ruciński and Tetali introduced two variants of a single‐player game whose goal is to colour the edges of a random graph, in an online fashion, so as not to create a monochromatic triangle.
