Diffeomorphisms as quadratic charges in 4d BF theory and related TQFTs
Journal of High Energy Physics, 2023 We present a Sugawara-type construction for boundary charges in 4d BF theory and in a general family of related TQFTs. Starting from the underlying current Lie algebra of boundary symmetries, this gives rise to well-defined quadratic charges forming an ...

Vector-Valued Modular Forms from the Mumford Form, Schottky-Igusa Form, Product of Thetanullwerte and the Amazing Klein Formula [PDF]
, 2012 Vector-valued Siegel modular forms are the natural generalization of the classical elliptic modular forms as seen by studying the cohomology of the universal abelian variety.

Control of Modular Multilevel Converters Using an Overlapping Multihexagon Space Vector Modulation Scheme [PDF]
IEEE Journal of Emerging and Selected Topics in Power Electronics, 2019 This paper introduces a novel space vector modulation scheme that can be applied for the control of modular multilevel cascaded converters (MMCCs) with any number of levels. This is achieved by using basic two-level or three-level hexagons to determine the switch states and the duty cycles separately within one tier of the converter which is a cascade ...

Freely acting orbifolds of type IIB string theory on T 5
Journal of High Energy Physics, 2023 We study freely acting orbifolds of type IIB string theory on T 5 that spontaneously break supersymmetry from N $$ \mathcal{N} $$ = 8 to N $$ \mathcal{N} $$ = 6, 4, 2 or 0 in five dimensions.

Algebraic formulas for the coefficients of mock theta functions and Weyl vectors of Borcherds products [PDF]
, 2017 We present some applications of the Kudla-Millson and the Millson theta lift. The two lifts map weakly holomorphic modular functions to vector valued harmonic Maass forms of weight $3/2$ and $1/2$, respectively.

On automorphisms of moduli spaces of parabolic vector bundles [PDF]
, 2019 Fix $n\geq 5$ general points $p_1, \dots, p_n\in\mathbb{P}^1$, and a weight vector $\mathcal{A} = (a_{1}, \dots, a_{n})$ of real numbers $0 \leq a_{i} \leq 1$.

Sequential Data Fusion via Vector Spaces: Complex Modular Neural Network Approach [PDF]
2005 IEEE Workshop on Machine Learning for Signal Processing, 2006 A data fusion approach based on complex and hyper-complex vectors spaces is presented. The benefits of such an approach are highlighted and potential applications are identified. A case study on simultaneous forecasting of wind speed and direction in the complex domain, together with a distributed serial sensor fusion topology illustrate the potential ...

Energies, 2022 Modular multilevel converter (MMC) is distinguished by its modularity. In order to improve its reliability and avoid unscheduled maintenance, it requires the MMC to continue operating even though some of its submodules (SMs) have failed. In this paper, a
