Global Graph Surrogates and Neural Graph Elements for Computational Mechanics

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.
ABSTRACT Machine learning surrogates are increasingly used to accelerate physics‐based simulations by predicting full‐field responses at a fraction of the computational cost. In this contribution, we present two complementary graph‐based approaches for surrogate modelling in computational mechanics.

Stable Cuts, NAC‐Colourings and Flexible Realisations of Graphs

Journal of Graph Theory, Volume 113, Issue 3, Page 411-427, November 2026.
ABSTRACT A (2‐dimensional) realisation of a graph G is a pair ( G , p ), where p maps the vertices of G to R 2. A realisation is flexible if it can be continuously deformed while keeping the edge lengths fixed, and rigid otherwise. We say that G is rigid if every generic realisation of G is rigid; otherwise, G is flexible. In this paper, we investigate

Chordal Graphs as Intersection Graphs of Pseudosegments

, 2007
We investigate which chordal graphs have a representation as intersection graphs of pseudosegments. The main contribution is a construction which shows that all chordal graphs which have a representation as intersection graph of subpaths on a tree are ...

Chordal Graphs and Their Relatives: Algorithms and Applications [PDF]

, 2020
While the problem of generating random graphs has received much attention, the problem of generating graphs for specific classes has not been studied much. In this dissertation, we propose schemes for generating chordal graphs, weakly chordal graphs, and

Weak Degeneracy of Planar Graphs

Journal of Graph Theory, Volume 113, Issue 3, Page 399-410, November 2026.
ABSTRACT The weak degeneracy of a graph G is a numerical parameter that was recently introduced by the first two authors with the aim of understanding the power of greedy algorithms for graph coloring. Every d‐degenerate graph is weakly d‐degenerate, but the converse is not true in general (e.g., all connected d‐regular graphs except cycles and cliques

On the Computational Complexity of Matching on Chordal and Strongly Chordal Graphs

, 1994
In this paper we study the computational complexity (both sequential and parallel) of the maximum matching problem for chordal and strongly chordal graphs.

A Min–Max Relation on Dicuts and Dijoins in Weighted Chordal Digraphs

Journal of Graph Theory, Volume 113, Issue 3, Page 462-469, November 2026.
ABSTRACT In a digraph, a dicut is a cut where all the arcs cross in one direction. A dijoin is a subset of arcs that intersects every dicut. Edmonds and Giles conjectured that in a weighted digraph, the minimum weight of a dicut is equal to the maximum size of a packing of dijoins. This has been disproved. However, the unweighted version conjectured by

Beyond Directions: Symmetry‐Aware Rotation Sets for Triaxial Diffusion Encoding by Geometric Filter Optimization

Magnetic Resonance in Medicine, Volume 96, Issue 5, Page 2489-2504, November 2026.
ABSTRACT Purpose To improve the accuracy of diffusion‐weighted powder average signals for diffusion encoding with arbitrary b‐tensors. Methods We identify an intrinsic dihedral (D2) symmetry of diffusion signals for arbitrary diffusion encoding, which defines their natural signal space (a quotient of 3D rotations). Based on this, we propose a method to

ManyBabies 3: A Multi‐Lab Study of Infant Algebraic Rule Learning

Developmental Science, Volume 29, Issue 6, November 2026.
ABSTRACT The ability to learn and apply rules lies at the heart of cognition. In a seminal study, Marcus et al. (1999) reported that 7‐month‐old infants learned abstract rules over syllable sequences and were able to generalize those rules to novel syllable sequences.

Entrepreneurial Market Leadership Claims, Cultural Resonance, and Investor Evaluations in Nascent Markets: The Goldilocks Effect

Journal of Management Studies, Volume 63, Issue 7, Page 3892-3930, November 2026.
Abstract Cultural entrepreneurship research emphasizes entrepreneurs’ use of cultural resources to influence audience evaluations through resonance. However, the process by which such cultural resonance is achieved remains underexplored, particularly as an intermediary outcome.
