Dual Feynman transform for modular operads [PDF]
, 2007 We introduce and study the notion of a dual Feynman transform of a modular operad. This generalizes and gives a conceptual explanation of Kontsevich's dual construction producing graph cohomology classes from a contractible differential graded Frobenius ...

On Some Modular Köthe Vector Valued Sequence Space using φ-Function
Journal of Physics: Conference Series, 2020 Abstract In this paper, we introduce some new modular vector valued sequence spaces defined by φ-function and give some basic result of this space.

, 2016 By an odd structure we mean an algebraic structure in the category of graded vector spaces whose structure operations have odd degrees. Particularly important are odd modular operads which appear as Feynman transforms of modular operads and, as such ...

Intertwining operators and vector-valued modular forms for minimal models [PDF]
, 2016 Using the language of vertex operator algebras (VOAs) and vector-valued modular forms we study the modular group representations and spaces of 1-point functions associated to intertwining operators for Virasoro minimal model VOAs.

IET Power Electronics, 2021 Abstract Modulation strategy plays an important role in the good performance of modular multilevel converter (MMC). Since MMC has a special structure as well as a large number of submodules (SMs), it is almost impossible to apply the conventional multilevel space vector modulation (SVM) algorithm in it. In this study, a simplified SVM

Space vector pulse width modulation strategy for modular multilevel converters in power system
IET Cyber-Physical Systems: Theory & Applications, 2023 Abstract As a superior modulation strategy, space vector pulse width modulation (SVPWM) provides redundant voltage vectors and adjustable action time, which can achieve multi‐objective control of modular multilevel converter (MMC). An SVPWM strategy suitable for MMC is proposed. The strategy is divided into three stages.

Basic vector valued Siegel modular forms of genus two [PDF]
, 2015 We consider the space of all vector-valued holomorphic modular forms f:H_n→Z of transformation type f(MZ)=vr(M)det(CZ+D)ϱ(CZ+D)f(Z). ϱ:GL(n,C)→GL(Z) is a rational representation on a finite dimensional complex vector space Z.

Modular topologies on vector spaces
This paper addresses the topological structures induced on vector spaces by convex modulars that do not satisfy the $Δ_2$ condition, with particular focus on their applications to variable exponent spaces such as \( \ell^{(p_n)} \) and \( L^{p(\cdot)} \).

, 1995 In this paper we consider a special class of arithmetic quotients of bounded symmetric domains which can roughly be described as higher- dimensional analogues of the Hilbert modular varities.
