How to see the forest despite the trees

Journal of the London Mathematical Society, Volume 114, Issue 2, August 2026.
Abstract One of the major starting points of discrete optimization is the theorem of Nash‐Williams and Tutte on the existence of k$k$ disjoint spanning trees of a graph, along with its counterpart on the existence of k$k$ forests covering all edges of the graph.

The asymptotic Mahler measure of Gaussian periods

Proceedings of the London Mathematical Society, Volume 133, Issue 2, August 2026.
Abstract We construct a sequence of cyclotomic integers (Gaussian periods) of particularly small Mahler measure/height. We study the asymptotics of their Mahler measure as a function of their conductor, to find that the growth rate is the (multivariate) Mahler measure of a family of log Calabi–Yau varieties of increasing dimension.

Manin's conjecture for integral points on toric varieties

Proceedings of the London Mathematical Society, Volume 133, Issue 2, August 2026.
Abstract We formulate a conjecture on the number of integral points of bounded height on log Fano varieties in analogy with Manin's conjecture on the number of rational points of bounded height on Fano varieties. We also give a prediction for the leading constant that is similar to Peyre's interpretation of the leading constant in Manin's conjecture ...

Skew shapes, Ehrhart positivity, and beyond

Proceedings of the London Mathematical Society, Volume 133, Issue 2, August 2026.
Abstract A classical result by Kreweras (1965) allows one to compute the number of plane partitions of a given skew shape and bounded parts as certain determinants. We prove that these determinants expand as polynomials with nonnegative coefficients.

Climate Change and (Mal)Adaptation in Tourism‐Intensive Alpine Regions

The Political Quarterly, Volume 97, Issue 3, Page 400-406, July/September 2026.
Abstract Tourism, especially in winter, accounts for a large share of economic income in Alpine regions. At the same time, these regions are more severely affected by climate change, leading to shorter winter seasons and reduced snow cover. This presents a pressing issue for areas reliant on income from winter tourism through activities such as skiing.

Iron Complexes With Proteins, Carbohydrates, and Maillard Products in Dairy Systems: Implication for Fortification, Bioavailability, and Product Functionality

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 4, July 2026.
ABSTRACT The global prevalence of iron (Fe) deficiency anemia (IDA) continues to pose major public health challenges, necessitating the development of effective fortification strategies. Dairy‐based systems are promising vehicles for Fe fortification and delivery due to their widespread consumption and nutritional value, although their complex matrix ...

Hyperbinary partitions and q-deformed rationals

Forum of Mathematics, Sigma
A hyperbinary partition of the nonnegative integer n is a partition where every part is a power of $2$ and every power of $2$ appears at most twice.

Regular Schur labeled skew shape posets and their 0-Hecke modules

Forum of Mathematics, Sigma
Assuming Stanley’s P-partitions conjecture holds, the regular Schur labeled skew shape posets are precisely the finite posets P with underlying set $\{1, 2, \ldots , |P|\}$ such that the P-partition generating function is symmetric and the set of ...

Properties of products for flatness in the category of $S$-posets [PDF]

Categories and General Algebraic Structures with Applications, 2016
