Relative commutator calculus in Chevalley groups
Journal of Algebra, 2013 We revisit localisation and patching method in the setting of Chevalley groups. Introducing certain subgroups of relative elementary Chevalley groups, we develop relative versions of the conjugation calculus and the commutator calculus in Chevalley groups $G(Φ,R)$, $\rk(Φ)\geq 2$, which are both more general, and substantially easier than the ones ...

Relative unitary commutator calculus, and applications [PDF]
Journal of Algebra, 2011 This note revisits localisation and patching method in the setting of generalised unitary groups. Introducing certain subgroups of relative elementary unitary groups, we develop relative versions of the conjugation calculus and the commutator calculus in unitary groups, which are both more general, and substantially easier than the ones available in ...

Non-Commutative Worlds and Classical Constraints [PDF]
Entropy, 2018 This paper reviews results about discrete physics and non-commutative worlds and explores further the structure and consequences of constraints linking classical calculus and discrete calculus formulated via commutators.

Time-dependent Hamiltonian Simulation of Highly Oscillatory Dynamics and Superconvergence for Schrödinger Equation [PDF]
Quantum, 2022 We propose a simple quantum algorithm for simulating highly oscillatory quantum dynamics, which does not require complicated quantum control logic for handling time-ordering operators.

Spectral multiplier theorems for abstract harmonic oscillators on UMD lattices
Comptes Rendus. Mathématique, 2023 We consider operators acting on a UMD Banach lattice $X$ that have the same algebraic structure as the position and momentum operators associated with the harmonic oscillator $-\frac{1}{2}\Delta + \frac{1}{2}|x|^{2} $ acting on $L^{2}(\mathbb{R}^{d ...

EXPTIME tableaux for the coalgebraic mu-calculus [PDF]
, 2011 The coalgebraic approach to modal logic provides a uniform framework that captures the semantics of a large class of structurally different modal logics, including e.g. graded and probabilistic modal logics and coalition logic.

Non-commutative functional calculus: Unbounded operators [PDF]
Journal of Geometry and Physics, 2009 In a recent work, \cite{cgss}, we developed a functional calculus for bounded operators defined on quaternionic Banach spaces. In this paper we show how the results from \cite{cgss} can be extended to the unbounded case, and we highlight the crucial differences between the two cases.

A Geometric Study of Commutator Subgroups [PDF]
, 2009 Let G be a group and G' its commutator subgroup. Commutator length (cl) and stable commutator length (scl) are naturally defined concepts for elements of G'. We study cl and scl for two classes of groups.
