Commutator Length of Finitely Generated Linear Groups
International Journal of Mathematics and Mathematical Sciences, 2008 The commutator length “cl(𝐺)” of a group 𝐺 is the least natural number 𝑐 such that every element of the derived subgroup of 𝐺 is a product of 𝑐 commutators.

Placebo in Paediatric Clinical Trials: Systematic Literature Review and Framework‐Based Synthesis
Journal of Paediatrics and Child Health, EarlyView.ABSTRACT Introduction Placebo‐controlled trials can provide strong evidence on safety and efficacy, but their ethical acceptability in paediatric research is contested because children have limited decisional capacity and placebo use may entail withholding effective therapy.

𝑛-dimensional projective varieties with the action of an abelian group of rank 𝑛-1
Transactions of the American Mathematical Society, 2016 Let X X be a normal projective variety of dimension n ≥ 3 n \ge 3 admitting the action of the group G := Z ⊕ n − 1 G := \mathbb {Z}^{\oplus n-1} such that ...

, 2017 We determine positive-dimensional G-periodic proper subvarieties of an n-dimensional normal projective variety X under the action of an abelian group G of maximal rank n-1 and of positive entropy.

Aggregation and the Structure of Value
Noûs, EarlyView.ABSTRACT Roughly, the view I call “Additivism” sums up value across time and people. Given some standard assumptions, I show that Additivism follows from two principles. The first says that how lives align in time cannot, in itself, matter. The second says, roughly, that a world cannot be better unless it is better within some period or another.

Physics Letters B, 2015 Working with explicit examples given by the 56 representation in SU(8), and the 10 representation in SU(5), we show that symmetry breaking of a group G⊃G1×G2 by a scalar in a rank three or two antisymmetric tensor representation leads to a number of ...

The large-N limit of the 4d N $$ \mathcal{N} $$ = 1 superconformal index
Journal of High Energy Physics, 2020 We systematically analyze the large-N limit of the superconformal index of N $$ \mathcal{N} $$ = 1 superconformal theories having a quiver description.

Compact K\"ahler manifolds admitting large solvable groups of automorphisms
, 2015 Let G be a group of automorphisms of a compact K\"ahler manifold X of dimension n and N(G) the subset of null-entropy elements. Suppose G admits no non-abelian free subgroup.

Analytic Philosophy, EarlyView.ABSTRACT Laws play some role in explanations: at the very least, they somehow connect what is explained, or the explanandum, to what explains, or the explanans. Thus, thermodynamical laws connect the match's being struck and its lightning, so that the former causes the latter; and laws about set formation connect Socrates' existence with {Socrates}'s ...

Rational points on even‐dimensional Fermat cubics
Transactions of the London Mathematical Society, Volume 13, Issue 1, December 2026.Abstract We show that even‐dimensional Fermat cubic hypersurfaces are rational over any field of characteristic not equal to three, by constructing explicit rational parameterizations with polynomials of low degree. As a byproduct of our rationality constructions, we obtain estimates for the number of their rational points over a number field and ...
