Discrete Mathematics & Theoretical Computer Science, 2004 Motivated by the Coxeter complex associated to a Coxeter system (W,S), we introduce a simplicial regular cell complex Δ (G,S) with a G-action associated to any pair (G,S) where G is a group and S is a finite set of generators for G which is minimal with ...

Symmetric Chain Decompositions and the Strong Sperner Property for Noncrossing Partition Lattices [PDF]
Discrete Mathematics & Theoretical Computer Science, 2020 We prove that the noncrossing partition lattices associated with the complex reflection groups G(d, d, n) for d, n ≥ 2 admit a decomposition into saturated chains that are symmetric about the middle ranks.

Quasi-invariants of complex reflection groups [PDF]
Compositio Mathematica, 2010 Abstract We introduce quasi-invariant polynomials for an arbitrary finite complex reflection group W . Unlike in the Coxeter case, the space of quasi-invariants of a given multiplicity is not, in general, an algebra but a module Q

DUNKL OPERATORS FOR COMPLEX REFLECTION GROUPS [PDF]
Proceedings of the London Mathematical Society, 2003 Dunkl operators for complex reflection groups are defined in this paper. These commuting operators give rise to a parameterized family of deformations of the polynomial De Rham complex. This leads to the study of the polynomial ring as a module over the ‘rational Cherednik algebra’, and a natural contravariant form on this module.

Non-Hermitian control between absorption and transparency in perfect zero-reflection magnonics
Nature Communications, 2023 Recent works in metamaterials and transformation optics have demonstrated exotic properties in a number of open systems, including perfect absorption/transmission, electromagnetically induced transparency, cloaking or invisibility, etc.

The Hurwitz action in complex reflection groups
Combinatorial Theory, 2022 We enumerate Hurwitz orbits of shortest reflection factorizations of an arbitrary element in the infinite family $G(m, p, n)$ of complex reflection groups. As a consequence, we characterize the elements for which the action is transitive and give a simple criterion to tell when two shortest reflection factorizations belong to the same Hurwitz orbit. We

Social Work and policy practice: group reflection and policy inquiry
Social Work and Society, 2022 Social policy in social work can be taught as rules articulated in documents. But the policy work in professional practice is more complex - it involves not only knowing what policy says but also how it works and how to make it work.

AUTOMORPHISM GROUPS OF THE IMPRIMITIVE COMPLEX REFLECTION GROUPS [PDF]
Journal of the Australian Mathematical Society, 2009 AbstractWe describe the group of all reflection-preserving automorphisms of an imprimitive complex reflection group. We also study some properties of this automorphism group.

Re-organise: Game-Based Learning of Circular Business Model Innovation
Frontiers in Sustainability, 2022 This study furthers game-based learning for circular business model innovation (CBMI), the complex, dynamic process of designing business models according to the circular economy principles.
