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.

Journal of Combinatorial Theory, Series A, 1988 A poset of shuffles is defined as follows: Let \b{x}\(=x_ 1x_ 2...x_ m\) and \b{y}\(=y_ 1y_ 2...y_ m\) be words, where it is assumed that the letters occurring in \b{x} and \b{y} are all distinct. Let \(W_{\underline x,\underline y}\) denote the set of all words \b{w} with letters from \b{x} and \b{y} such that the restriction of \b{w} to the letters ...

Probability Functions on Posets
Mathematics, 2019 In this paper, we define the notion of a probability function on a poset which is similar to the probability function discussed on d-algebras, and obtain three probability functions on posets. Moreover, we define a probability realizer of a poset, and we

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.

Order, 2020 A collection of linear orders on $X$, say $\mathcal{L}$, is said to \emph{realize} a partially ordered set (or poset) $\mathcal{P} = (X, \preceq)$ if, for any two distinct $x,y \in X$, $x \preceq y$ if and only if $x \prec_L y$, $\forall L \in \mathcal{L}$. We call $\mathcal{L}$ a \emph{realizer} of $\mathcal{P}$. The \emph{dimension} of $\mathcal{P}$,

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 ...

Journal of Combinatorial Theory, Series A, 1993 One sure sign of a successful generalization of a particular theory is an extension of language and technique to a larger domain permitting one to reconstruct considerable parts of previous theory on such a new basis. Another such sign is to provide new interpretations and insights captured by such an extended theory, especially involving results ...

Maximum distance separable poset codes
, 2018 We derive the Singleton bound for poset codes and define the MDS poset codes as linear codes which attain the Singleton bound. In this paper, we study the basic properties of MDS poset codes.
