Feedback linearization of possibly non-smooth systems; pp. 109–123 [PDF]
Proceedings of the Estonian Academy of Sciences, 2017 The algebraic approach known as functionsâ algebra is used to develop the necessary and sufficient conditions for the existence of state transformation and static state feedback that linearize the system equations.

What Group Theory Can Do for You: From Magmas to Abstract Thinking in School Mathematics
Mathematics, 2022 In this paper, we present a novel concept for an abstract algebra course at the secondary school level. Against the backdrop of findings from mathematics education research, we discuss benefits that arise from teaching abstract algebra to secondary ...

Approaching Algebra through Sequence Problems: Exploring children's strategies [PDF]
, 2003 We describe the first phase of a project concerned with the foundations of algebra. Data consists of the responses of 11 year-olds to selected questions from national tests.

CENTRAL SEQUENCE ALGEBRAS OF VON NEUMANN ALGEBRAS
Taiwanese Journal of Mathematics, 2006 We prove that the ultrapower and the central sequence algebra of the hyperfinite II1 factor are prime factors which implies that the central sequence algebra of the tensor product of two factors may not be the tensor product of the central sequence algebras of the factors respectively. This answers negatively a question of D. McDuff.

, 2004 To every vertex algebra $V$ we associate a canonical decreasing sequence of subspaces and prove that the associated graded vector space $gr(V)$ is naturally a vertex Poisson algebra, in particular a commutative vertex algebra.

Group C*-algebras as decreasing intersection of nuclear C*-algebras
, 2016 We prove that for every exact discrete group $\Gamma$, there is an intermediate C*-algebra between the reduced group C*-algebra and the intersection of the group von Neumann algebra and the uniform Roe algebra which is realized as the intersection of a ...

Holomorphic Functions and polynomial ideals on Banach spaces [PDF]
, 2010 Given $\u$ a multiplicative sequence of polynomial ideals, we consider the associated algebra of holomorphic functions of bounded type, $H_{b\u}(E)$. We prove that, under very natural conditions verified by many usual classes of polynomials, the spectrum

Maximal green sequences for cluster-tilted algebras of finite representation type [PDF]
, 2018 We show that, for any cluster-tilted algebra of finite representation type over an algebraically closed field, the following three definitions of a maximal green sequence are equivalent: (1) the usual definition in terms of Fomin-Zelevinsky mutation of ...

Newton-Hooke/Carrollian expansions of (A)dS and Chern-Simons gravity
Journal of High Energy Physics, 2020 We construct finite- and infinite-dimensional non-relativistic extensions of the Newton-Hooke and Carroll (A)dS algebras using the algebra expansion method, starting from the (anti-)de Sitter relativistic algebra in D dimensions.
