Face counting formula for toric arrangements defined by root systems
AKCE International Journal of Graphs and Combinatorics, 2019 A toric arrangement is a finite collection of codimension-1 subtori in a torus. The intersections of these subtori stratify the ambient torus into faces of various dimensions.

Morphisms and Order Ideals of Toric Posets
Mathematics, 2016 Toric posets are in some sense a natural “cyclic” version of finite posets in that they capture the fundamental features of a partial order but without the notion of minimal or maximal elements.

Affine and toric arrangements [PDF]
Discrete Mathematics & Theoretical Computer Science, 2008 We extend the Billera―Ehrenborg―Readdy map between the intersection lattice and face lattice of a central hyperplane arrangement to affine and toric hyperplane arrangements.

Wonderful compactifications and rational curves with cyclic action
Forum of Mathematics, Sigma, 2023 We prove that the moduli space of rational curves with cyclic action, constructed in our previous work, is realizable as a wonderful compactification of the complement of a hyperplane arrangement in a product of projective spaces.

Combinatorial Topology of Toric arrangements [PDF]
Discrete Mathematics & Theoretical Computer Science, 2013 We prove that the complement of a complexified toric arrangement has the homotopy type of a minimal CW-complex, and thus its homology is torsion-free.

ON TORUS ACTIONS OF HIGHER COMPLEXITY
Forum of Mathematics, Sigma, 2019 We systematically produce algebraic varieties with torus action by constructing them as suitably embedded subvarieties of toric varieties. The resulting varieties admit an explicit treatment in terms of toric geometry and graded ring theory. Our approach

LOCAL SYSTEMS ON COMPLEMENTS OF ARRANGEMENTS OF SMOOTH, COMPLEX ALGEBRAIC HYPERSURFACES
Forum of Mathematics, Sigma, 2018 We consider smooth, complex quasiprojective varieties $U$ that admit a compactification with a boundary, which is an arrangement of smooth algebraic hypersurfaces. If the hypersurfaces intersect locally like hyperplanes,

Elliptic arrangements of complex multiplication type
Forum of Mathematics, SigmaWe provide a natural definition of an elliptic arrangement, extending the classical framework to an elliptic curve $\mathcal {E}$ with complex multiplication.

Business Strategy and the Environment, EarlyView.ABSTRACT The circular economy (CE) has become a major focus in energy and environmental (E&E) research, as it helps advance sustainable development, improve resource efficiency and alleviate environmental pressure. Even so, the literature is still fragmented, particularly in the CE themes it explores, the levels of analysis it adopts and the methods ...

The Multilevel Implications of a Sinn Féin Government in Ireland
The Political Quarterly, Volume 96, Issue 1, Page 173-179, January/March 2025.Abstract The electoral growth of Sinn Féin on both sides of the Irish border has generated much political and academic attention in recent years. The party could form part of the government in Dublin for the first time at the next Irish general election, though that outcome is far from certain.
