Fermionic T-duality and U-duality in type II supergravity [PDF]

open access: yes, 2011
PhDThis thesis deals with the two duality symmetries of N = 2 D = 10 supergravity theories that are descendant from the full superstring theory: fermionic T-duality and U-duality.

Arithmetic matroids and Tutte polynomials [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2012
We introduce the notion of arithmetic matroid, whose main example is provided by a list of elements in a finitely generated abelian group. We study the representability of its dual, and, guided by the geometry of toric arrangements, we give a ...

Fan realizations of type $A$ subword complexes and multi-associahedra of rank 3 [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2015
We present complete simplicial fan realizations of any spherical subword complex of type $A_n$ for $n\leq 3$. This provides complete simplicial fan realizations of simplicial multi-associahedra $\Delta_{2k+4,k}$, whose facets are in correspondence with ...

T-duality invariant approaches to string theory [PDF]

open access: yes, 2010
PhDThis thesis investigates the quantum properties of T-duality invariant formalisms of String Theory. We introduce and review duality invariant formalisms of String Theory including the Doubled Formalism.

Linear difference equations, frieze patterns, and the combinatorial Gale transform

open access: yesForum of Mathematics, Sigma, 2014
We study the space of linear difference equations with periodic coefficients and (anti)periodic solutions. We show that this space is isomorphic to the space of tame frieze patterns and closely related to the moduli space of configurations of points in ...

Assessing the Environmental Consequences of the Generation and Alteration of Mafic Volcaniclastic Deposits During Large Igneous Province Emplacement

open access: yesGeophysical Monograph Series, Page 117-131., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Gale duality and Koszul duality [PDF]

open access: yes, 2008
Given an affine hyperplane arrangement with some additional structure, we define two finite-dimensional, noncommutative algebras, both of which are motivated by the geometry of hypertoric varieties.

Weather Action: A Study on the Industry Peer Effects of Corporate Climate Risk Information Disclosure

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Global climate change has elevated the strategic importance of corporate climate risk disclosure, yet the role of industry peer effects in shaping such disclosure remains underexplored. Grounded in social learning theory, this study proposes an “observation–imitation–reinforcement” framework and empirically tests it using panel data on Chinese

On the duality gap and Gale's example in conic linear programming

open access: yes, 2022
The aim of this paper is to revisit some duality results in conic linear programming and to answer an open problem related to the duality gap function for Gale's example.
