Flavor, CP and metaplectic modular symmetries in Type IIB chiral flux vacua
Journal of High Energy Physics, 2023 We examine symmetries of chiral four-dimensional vacua of Type IIB flux compactifications with vanishing superpotential W = 0. We find that the N $$ \mathcal{N} $$ = 1 supersymmetric MSSM-like and Pati-Salam vacua possess enhanced discrete symmetries in ...

Observer‐Based Adaptive Event‐Triggered Tracking Control for Fuzzy TS Systems With Premise Mismatch
International Journal of Adaptive Control and Signal Processing, EarlyView.This paper presents an adaptive logistic event‐triggered observer‐based tracking controller for Takagi‐Sugeno fuzzy systems under constrained inputs and network delays. Leveraging a hybrid LMI and Secretary Bird Optimization approach, this strategy significantly minimizes communication overhead and computational burden while ensuring optimal reference ...

Minimal eclectic flavor group Q 8 ⋊ S 3 and neutrino mixing
Journal of High Energy PhysicsWe perform a comprehensive analysis of the minimal eclectic flavor group Q 8 ⋊ S 3 which is isomorphic to GL(2, 3), and all its irreducible representations are induced from the irreducible representations of Q 8 and S 3.

Note on gauge and gravitational anomalies of discrete Z N symmetries
Journal of High Energy Physics, 2018 In this note, we discuss the consistency conditions which a discrete Z N symmetry should satisfy in order that it is not violated by gauge and gravitational instantons.

Lie symmetry, discrete symmetry and supersymmetry of the Pauli Hamiltonian [PDF]
Czechoslovak Journal of Physics, 2001 Starting from the full group of symmetries of a system we select a discrete subset of transformations which allows to introduce the Clifford algebra of operators generating new supercharges of extended supersymmetry. The system defined by the Pauli Hamiltonian is discussed.

A Workflow to Accelerate Microstructure‐Sensitive Fatigue Life Predictions
Advanced Engineering Materials, EarlyView.This study introduces a workflow to accelerate predictions of microstructure‐sensitive fatigue life. Results from frameworks with varying levels of simplification are benchmarked against published reference results. The analysis reveals a trade‐off between accuracy and model complexity, offering researchers a practical guide for selecting the optimal ...

Symmetries for the Semi-Discrete Lattice Potential Korteweg–de Vries Equation
MathematicsIn this paper, we prove that the isospectral flows associated with both the x-part and the n-part of the Lax pair of the semi-discrete lattice potential Korteweg–de Vries equation are symmetries of the equation.

Discrete symmetries with neutral mesons
EPJ Web of Conferences, 2018 Symmetries, and Symmetry Breakings, in the Laws of Physics play a crucial role in Fundamental Science. Parity and Charge Conjugation Violations prompted the consideration of Chiral Fields in the construction of the Standard Model, whereas CP-Violation ...

ON PARTIAL DIFFERENTIAL AND DIFFERENCE EQUATIONS WITH SYMMETRIES DEPENDING ON ARBITRARY FUNCTIONS
Acta Polytechnica, 2016 In this note we present some ideas on when Lie symmetries, both point and generalized, can depend on arbitrary functions. We show a few examples, both in partial differential and partial difference equations where this happens.
