Journal of Management Studies, Volume 61, Issue 7, Page 3081-3107, November 2024.Abstract We contribute to the literature on acquisitions by examining how investors’ cognitive schemata codifying their beliefs concerning the attributes of deal success (‘recipes’) are impacted by systemic crises. Specifically, we examine how and why configurations of attributes signalling deal attractiveness, acquirer competence, and acquirer ...

Mathematics discovered, invented, and inherited [PDF]
, 2013 The classical platonist/formalist dilemma in philosophy of mathematics can be expressed in lay terms as a deceptively naive question: is new mathematics discovered or invented?

Recovering p$p$‐adic valuations from pro‐p$p$ Galois groups
Journal of the London Mathematical Society, Volume 109, Issue 5, May 2024.Abstract Let K$K$ be a field with GK(2)≃GQ2(2)$G_K(2) \simeq G_{\mathbb {Q}_2}(2)$, where GF(2)$G_F(2)$ denotes the maximal pro‐2 quotient of the absolute Galois group of a field F$F$. We prove that then K$K$ admits a (non‐trivial) valuation v$v$ which is 2‐henselian and has residue field F2$\mathbb {F}_2$. Furthermore, v(2)$v(2)$ is a minimal positive

Weak weak approximation and the Hilbert property for degree 2 del Pezzo surfaces
Proceedings of the London Mathematical Society, Volume 128, Issue 5, May 2024.Abstract We prove that del Pezzo surfaces of degree 2 over a field k$k$ satisfy weak weak approximation if k$k$ is a number field and the Hilbert property if k$k$ is Hilbertian of characteristic zero, provided that they contain a k$k$‐rational point lying neither on any 4 of the 56 exceptional curves nor on the ramification divisor of the anticanonical

Fractional Brauer configuration algebras III: fractional Brauer graph algebras in type MS
In previous papers, we defined fractional Brauer graphs and studied their covering theory. In this paper, we develop a covering theory for the Brauer $G$-sets and use it to generalize the representation type results and the AR-components results on Brauer graph algebras to the scope of fractional Brauer graph algebras in type MS.

Decomposition numbers for abelian defect RoCK blocks of double covers of symmetric groups
Journal of the London Mathematical Society, Volume 109, Issue 2, February 2024.Abstract We calculate the (super)decomposition matrix for a RoCK block of a double cover of the symmetric group with abelian defect, verifying a conjecture of the first author. To do this, we exploit a theorem of the second author and Livesey that a RoCK block Bρ,d$\mathcal {B}^{\rho,d}$ is Morita superequivalent to a wreath superproduct of a certain ...
