British Journal of Developmental Psychology, EarlyView.Abstract Acquiring mathematical competence is essential to independent living. In this study, we investigated the mathematics profile in young people with Down syndrome (DS), and the relations between foundational and more complex mathematics skills.

The singularity obstruction for group splittings [PDF]
, 2002 We study an obstruction to splitting a finitely generated group G as an amalgamated free product or HNN extension over a given subgroup H and show that when the obstruction is "small" G splits over a related subgroup.

Scalable Computation of Topological Abstractions for Scalar Data
Computer Graphics Forum, EarlyView.Abstract Topological data analysis has become an important tool for large scale scalar data analysis and visualization, efficiently extracting the inherent structure and features of interest of the data. However, with growing dataset sizes and complexity, it is increasingly becoming infeasible to compute topological abstractions of interest in serial ...

On some subvarieties of IMTn-algebras and the partitions of the m-cube
Algebra universalis, 2014 Prelinear, bounded, integral, residuated, commutative lattices form the variety \(\mathbb{MTL}\) of MTL-algebras, which in turn constitutes the algebraic semantics of the logic of all left-continuous t-norms. The paper studies some subvarieties of \(\mathbb{MTL}\).

ON THE STABLE RANK OF ALGEBRAS OF OPERATOR FIELDS OVER AN $N$-CUBE [PDF]
Bulletin of the London Mathematical Society, 2004 Summary: Let \({\mathcal A}\) be a unital maximal full algebra of operator fields with base space \([0,1]^k\) and fibre algebras \(\{{\mathcal A}_t\}^k_{t\in[0,1]}\). It is shown in this paper that the stable rank of \({\mathcal A}\) is bounded above by the quantity \(\sup_{t\in[0,1]^k}\text{sr}(C([0,1]^k)\otimes{\mathcal A}_t)\), where `sr' means ...

The Role of Dice in the Emergence of the Probability Calculus
International Statistical Review, EarlyView.Summary The early development of the probability calculus was clearly influenced by the roll of dice. However, while dice have been cast since time immemorial, documented calculations on the frequency of various dice throws date back only to the mid‐13th century.

Measure‐valued processes for energy markets
Mathematical Finance, Volume 35, Issue 2, Page 520-566, April 2025.Abstract We introduce a framework that allows to employ (non‐negative) measure‐valued processes for energy market modeling, in particular for electricity and gas futures. Interpreting the process' spatial structure as time to maturity, we show how the Heath–Jarrow–Morton approach can be translated to this framework, thus guaranteeing arbitrage free ...

Solving Stochastic Climate‐Economy Models: A Deep Least‐Squares Monte Carlo Approach
Mathematical Finance, EarlyView.ABSTRACT Stochastic versions of recursive integrated climate‐economy assessment models are essential for studying and quantifying policy decisions under uncertainty. However, as the number of state variables and stochastic shocks increases, solving these models via deterministic grid‐based dynamic programming (e.g., value‐function iteration/projection ...
