Beyond Substitution—An Antipositionalist's Guide to Subtraction—

Philosophy and Phenomenological Research, EarlyView.
ABSTRACT Existing accounts of relations do not properly account for variably polyadic relations: they fail to capture the relationship between completions of the same relation by different numbers of relata. This paper develops a fully general account of such relations by adding an operation of subtraction to the antipositionalist theory of relations ...

On families of K3 surfaces with real multiplication

Forum of Mathematics, Sigma
We exhibit large families of K3 surfaces with real multiplication, both abstractly, using lattice theory, the Torelli theorem and the surjectivity of the period map, as well as explicitly, using dihedral covers and isogenies.

Beyond Boolean Surjective VCSPs.

CoRR, 2019
Fulla, Uppman, and Živný [ACM ToCT’18] established a dichotomy theorem for Boolean surjective general-valued constraint satisfaction problems (VCSPs), i.e., VCSPs on two-element domains in which both labels have to be used in a solution. This result, in addition to identifying the complexity frontier, features the discovery of a new non-trivial ...

On computing local monodromy and the numerical local irreducible decomposition

Transactions of the London Mathematical Society, Volume 13, Issue 1, December 2026.
Abstract Similarly to the global case, the local structure of a holomorphic subvariety at a given point is described by its local irreducible decomposition. Geometrically, the key requirement for obtaining a local irreducible decomposition is to compute the local monodromy action of a generic linear projection at the given point, which is always well ...

Surjective multiband linear cellular automata and Smith's normal form

Publicaciones en Ciencias y Tecnología, 2009
In this paper the Smith normal form of certain matrices is used to provide another char acterization for the surjectivity of one-dimensional linear cellular automata with multiple local rules over the ring ZN of integers modulo N ≥ 2..

A NOTE ON SURJECTIVE CARDINALS

The Journal of Symbolic Logic
Abstract For cardinals $\mathfrak {a}$ and $\mathfrak {b}$ , we write $\mathfrak {a}=^\ast \mathfrak {b}$ if there are sets A and B of cardinalities $\mathfrak {a}$ and $\mathfrak {b}$ , respectively ...

On the additive image of zeroth persistent homology

Transactions of the London Mathematical Society, Volume 13, Issue 1, December 2026.
Abstract For a category X$X$ and a finite field F$F$, we study the additive image of the functor H0(−;F)∗:rep(X,Top)→rep(X,VectF)$\operatorname{H}_0(-;F)_* \colon \operatorname{rep}(X, \mathbf {Top}) \rightarrow \operatorname{rep}(X, \mathbf {Vect}_F)$, or equivalently, of the free functor rep(X,Set)→rep(X,VectF)$\operatorname{rep}(X, \mathbf {Set ...

On the alternating use of unanimity and surjectivity in the Gibbard-Satterthwaite Theorem

, 2007
Surjectivity and unanimity can be equivalently used to state the Gibbard-Satterthwaite Theorem. On the other hand, over restricted domains, replacing surjectivity with unanimity makes a stronger statement. (c) 2007 Elsevier B.V.

On the automorphisms of the power semigroups of a numerical semigroup

Transactions of the London Mathematical Society, Volume 13, Issue 1, December 2026.
Abstract If H$H$ is a numerical semigroup (i.e., a cofinite subset of the non‐negative integers closed under addition), then the collection of all non‐empty subsets of H$H$ forms a semigroup P(H)$\mathcal {P}(H)$ under the sumset operation induced by addition in H$H$.

Some results on surjectivity of augmented differential operators

, 2012
Considering a problem of Bonet and Domański (2006) [1, Problem 9.1], we prove that for a polynomial P on R2 surjectivity of the differential operator P(D) on D′(X) implies surjectivity of the augmented operator P+(D) on D′(X×R), where P+(x1,x2,x3):=P(x1 ...
