Convex Combinatorial Optimization [PDF]
, 2003 We introduce the convex combinatorial optimization problem, a far reaching generalization of the standard linear combinatorial optimization problem. We show that it is strongly polynomial time solvable over any edge-guaranteed family, and discuss several

Steenrod operations via higher Bruhat orders
Proceedings of the London Mathematical Society, Volume 130, Issue 2, February 2025.Abstract The purpose of this paper is to establish a correspondence between the higher Bruhat orders of Yu. I. Manin and V. Schechtman, and the cup‐i$i$ coproducts defining Steenrod squares in cohomology. To any element of the higher Bruhat orders, we associate a coproduct, recovering Steenrod's original ones from extremal elements in these orders ...

Cost of Simulating Entanglement in Steering Scenarios [PDF]
QuantumQuantum entanglement is a fundamental feature of quantum mechanics, yet certain entangled states that are unsteerable can be classically simulated in steering scenarios, making them unable to exhibit quantum steering.

Hierarchical zonotopal spaces [PDF]
, 2010 Zonotopal algebra interweaves algebraic, geometric and combinatorial properties of a given linear map X. Of basic significance in this theory is the fact that the algebraic structures are derived from the geometry (via a non-linear procedure known as ...

A data‐driven safety preserving control architecture for constrained cyber‐physical systems
International Journal of Robust and Nonlinear Control, Volume 35, Issue 1, Page 343-358, 10 January 2025.Abstract In this article, we propose a data‐driven networked control architecture for unknown and constrained cyber‐physical systems capable of detecting networked false‐data‐injection attacks and ensuring plant's safety. In particular, on the controller's side, we design a novel robust anomaly detector that can discover the presence of network attacks

CAT(0) and cubulated Shephard groups
Journal of the London Mathematical Society, Volume 111, Issue 1, January 2025.Abstract Shephard groups are common generalizations of Coxeter groups, Artin groups, and graph products of cyclic groups. Their definition is similar to that of a Coxeter group, but generators may have arbitrary order rather than strictly order 2. We extend a well‐known result that Coxeter groups are CAT(0)$\mathrm{CAT}(0)$ to a class of Shephard ...

ERROR BOUNDS FOR SURFACE AREA ESTIMATORS BASED ON CROFTON’S FORMULA
Image Analysis and Stereology, 2011 According to Crofton's formula, the surface area S(A) of a sufficiently regular compact set A in Rd is proportional to the mean of all total projections pA (u) on a linear hyperplane with normal u, uniformly averaged over all unit vectors u.

On \pi-surfaces of four-dimensional parallelohedra [PDF]
, 2013 We show that every four-dimensional parallelohedron P satisfies a recently found condition of Garber, Gavrilyuk & Magazinov sufficient for the Voronoi conjecture being true for P. Namely we show that for every four-dimensional parallelohedron P the group

International Transactions on Electrical Energy Systems, Volume 2025, Issue 1, 2025.Flexible load resources on the demand side are characterized by diverse types, small capacity, and wide distribution. Since these load resources cannot be individually invoked at the system level, it is becoming increasingly important to consider how to establish heterogeneous flexible load aggregates and utilize their adjustable characteristics.
