$\boldsymbol{(n+2)}$-angulated functors induced by $\boldsymbol{n}$-exact functors [PDF]
SCIENTIA SINICA Mathematica, 2018 Let $(\mathcal{A},\mathscr{X})$ and $(\mathcal{A}',\mathscr{X}')$ be two Frobenius $n$-exact categories, and $F\colon\mathcal{A}\to\mathcal{A}'$ be an $n$-exactfunctor. If $F$ sends $\mathscr{X}$-injective objects in $\mathcal{A}$ to $\mathscr{X}'$-injective objects in $\mathcal{A}'$, then it induces an $(n+2)$-angulated functor $\overline{F}\colon ...

The Yoneda isomorphism commutes with homology
, 2015 We show that, for a right exact functor from an abelian category to abelian groups, Yoneda's isomorphism commutes with homology and, hence, with functor derivation. Then we extend this result to semiabelian domains.

Differential cohomology and locally covariant quantum field theory [PDF]
, 2016 We study differential cohomology on categories of globally hyperbolic Lorentzian manifolds. The Lorentzian metric allows us to define a natural transformation whose kernel generalizes Maxwell's equations and fits into a restriction of the fundamental ...

Can we repudiate ontology altogether?
Noûs, EarlyView.Abstract Ontological nihilists repudiate ontology altogether, maintaining that ontological structure is an unnecessary addition to our theorizing. Recent defenses of the view involve a sophisticated combination of highly expressive but ontologically innocent languages combined with a metaphysics of features—non‐objectual, complete but modifiable states

Theoria, EarlyView.Abstract This paper argues for the significance of Kaplan's logic LD in two ways: first, by looking at how logic got along before we had LD, and second, by using it to bring out the similarity between David Hume's thesis that one cannot deduce claims about the future on the basis of premises only about the past, and the so‐called "essentiality" of the ...

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 ...

3D MR Thermometry Using Bi‐Directional Segmented EPI for Transcranial‐Focused Ultrasound
Magnetic Resonance in Medicine, Volume 95, Issue 4, Page 2106-2116, April 2026.ABSTRACT Purpose To evaluate the feasibility of replacing clinically utilized 2D thermometry with 3D segmented EPI‐based thermometry with equivalent accuracy, precision, and scan time. Methods A 3D segmented EPI (segEPI) trajectory was modified to allow readouts along both the forward and reverse direction for each phase encoding line, and the sequence

Analytic vectors in continuous p-adic representations
, 2012 Given a compact p-adic Lie group G over a finite unramified extension L/Q_p let G_0 be the product over all Galois conjugates of G. We construct an exact and faithful functor from admissible G-Banach space representations to admissible locally L-analytic

Equivariant toric geometry and Euler–Maclaurin formulae
Communications on Pure and Applied Mathematics, Volume 79, Issue 3, Page 451-557, March 2026.Abstract We first investigate torus‐equivariant motivic characteristic classes of toric varieties, and then apply them via the equivariant Riemann–Roch formalism to prove very general Euler–Maclaurin‐type formulae for full‐dimensional simple lattice polytopes.
