Commutative ring spectra [PDF]
arXiv, 2017 In this survey paper on commutative ring spectra we present some basic features of commutative ring spectra and discuss model category structures. As a first interesting class of examples of such ring spectra we focus on (commutative) algebra spectra over commutative Eilenberg-MacLane ring spectra.

On commutator fully transitive Abelian groups
, 2015 There are two rather natural questions which arise in connection with the endomorphism ring of an Abelian group: when is the ring generated by its commutators, and when is the ring additively generated by its commutators?

Epilepsia, EarlyView.Abstract Electroencephalography (EEG) has been instrumental in epilepsy research for the past century, both for basic and translational studies. Its contributions have advanced our understanding of epilepsy, shedding light on the pathophysiology and functional organization of epileptic networks, and the mechanisms underlying seizures.

Spanning Multi‐Asset Payoffs With ReLUs
Mathematical Finance, EarlyView.ABSTRACT We propose a distributional formulation of the spanning problem of a multi‐asset payoff by vanilla basket options. This problem is shown to have a unique solution if and only if the payoff function is even and absolutely homogeneous, and we establish a Fourier‐based formula to calculate the solution.

Information and Computation, 1987 AbstractWe extend the notion of partial commutation by introducing that of semi-commutation which is its non-symetrical version. A semi-commutation function f is associated to a semi-Thue system 〈X, P〉 where the rules are of the form yx → xy with x, y ϵ X. We study this operation in connection with rational operations.

Compactness of the commutator of bilinear Fourier multiplier operator
, 2014 Let $b_1, b_2 \in {\rm CMO}(\mathbb{R}^n)$ and $T_{\sigma}$ be the bilinear Fourier multiplier operator with associated multiplier $\sigma$ satisfies the Sobolev regularity that $\sup_{\kappa\in \mathbb{Z}}\|\sigma_{\kappa}\|_{W^{s_1,\,s_2}(\mathbb{R ...

Where Mathematical Symbols Come From
Topics in Cognitive Science, EarlyView.Abstract There is a sense in which the symbols used in mathematical expressions and formulas are arbitrary. After all, arithmetic would be no different if we would replace the symbols ‘+$+$’ or ‘8’ by different symbols. Nevertheless, the shape of many mathematical symbols is in fact well motivated in practice.
