DO MONETARY AGGREGATES BELONG IN A MONETARY MODEL? EVIDENCE FROM THE UK
Buletin Ekonomi Moneter dan Perbankan, 2020 Conventional monetary models focus on interest rates and omit monetary aggregates from policy discussions. This paper examines whether augmenting the measure of monetary policy with monetary aggregates helps determine more robust links between policy and

Double affine Hecke algebras and bispectral quantum Knizhnik-Zamolodchikov equations [PDF]
, 2009 We use the double affine Hecke algebra of type GL_N to construct an explicit consistent system of q-difference equations, which we call the bispectral quantum Knizhnik-Zamolodchikov (BqKZ) equations.

On properties of the lower central series of associative algebras [PDF]
, 2015 We give an accessible introduction into the theory of lower central series of associative algebras, exhibiting the interplay between algebra, geometry and representation theory that is characteristic for this subject, and discuss some open questions.

On Groups with Finite Hirsch Number [PDF]
Advances in Group Theory and Applications, 2020 Suppose G is a group with finite Hirsch number h modulo the k-th term of its upper central series. The Hirsch number of the (k + 1)-th term of the lower central series of G is known to be finite and of order bounded in terms of h and k.

Multiscaling NDVI Series Analysis of Rainfed Cereal in Central Spain
Remote Sensing, 2021 Vegetation indices time series analysis is increasingly improved for characterizing agricultural land processes. However, this is challenging because of the multeity of factors affecting vegetation growth.

Proceedings of the Edinburgh Mathematical Society, 1962 Letandbe, respectively, the upper and lower central series of a group G. Our purpose in this note is to extend known results and find some information as to which of the factors Zk/Zk−1 and Γk/Γk+1 may be infinite. Though our conclusions about the lower central series will be quite general we assume in the other case that the group is f.n., i.e.

On Peiffer central series [PDF]
Glasgow Mathematical Journal, 1998 Let G be a group. A precrossed G-module is a group homomorphism ∂: M → G together with a group action (g, m) ↦gm of G on M, such that ∂(gm) = g(∂m)g−1. The Peiffer commutator < m, m′ > of two elements m, m′ ∊ M is denned as< m, m′ >= mm′ m−1(∂mm′)−1If all Peiffer commutators are trivial, the precrossed G-module is said to be a crossed G ...
