New Modular Fixed-Point Theorem in the Variable Exponent Spaces p(.)

open access: yesMathematics, 2022
In this work, we prove a fixed-point theorem in the variable exponent spaces ℓp(.), when p−=1 without further conditions. This result is new and adds more information regarding the modular structure of these spaces.

Smooth Compactifications of the Abel-Jacobi Section

open access: yesForum of Mathematics, Sigma, 2023
For $\theta $ a small generic universal stability condition of degree $0$ and A a vector of integers adding up to $-k(2g-2+n)$ , the spaces $\overline {\mathcal {M}}_{g,A}^\theta $ constructed in [AP21, HMP+22] are observed to ...

Space vector modulation method for modular multilevel converters [PDF]

open access: yesIECON 2014 - 40th Annual Conference of the IEEE Industrial Electronics Society, 2014
This paper presents a generalized space vector modulation (SVM) method for any modular multilevel converter (MMC). The proposed SVM method produces the maximum level number (i.e., 2«+l, where n is the number of submodules in the upper or lower arm of each phase) of the output phase voltages and a higher equivalent switching frequency than other ...

Research on Simplified SVPWM for Multilevel MMC-SVG

open access: yesZhejiang dianli, 2022
SVPWM (space vector pulse width modulation) is difficult to be applied to MMC (modular multilevel converter) control, the paper proposes an SVPWM applicable to arbitrary MMC.

Modular curves and the refined distance conjecture

open access: yesJournal of High Energy Physics, 2021
We test the refined distance conjecture in the vector multiplet moduli space of 4D N $$ \mathcal{N} $$ = 2 compactifications of the type IIA string that admit a dual heterotic description.

Orthogonality and complementation in the lattice of subspaces of a finite vector space [PDF]

open access: yesMathematica Bohemica, 2022
We investigate the lattice $ L( V)$ of subspaces of an $m$-dimensional vector space $ V$ over a finite field ${\rm GF}(q)$ with a prime power $q=p^n$ together with the unary operation of orthogonality.

Hybrid Modulation for Modular Voltage Source Inverters with Coupled Reactors

open access: yesEnergies, 2020
This paper proposes and discusses a concept of a hybrid modulation for the control of modular voltage source inverters with coupled reactors. The use of coupled reactors as the integrating elements leads to significant reduction in the size and weight of

Efficient Implementations of Sieving and Enumeration Algorithms for Lattice-Based Cryptography

open access: yesMathematics, 2021
The security of lattice-based cryptosystems is based on solving hard lattice problems such as the shortest vector problem (SVP) and the closest vector problem (CVP).

A p-adic Eisenstein measure for vector-weight automorphic forms [PDF]

open access: yes, 2014
We construct a p-adic Eisenstein measure with values in the space of vector-weight p-adic automorphic forms on certain unitary groups. This measure allows us to p-adically interpolate special values of certain vector-weight C-infinity automorphic forms ...
