Discrete symmetries of functional determinants [PDF]
Nuclear Physics B, 2001 We study discrete (duality) symmetries of functional determinants. An exact transformation of the effective action under the inversion of background fields $ (x) \to ^{-1}(x)$ is found. We show that in many cases this inversion does not change functional determinants.

Communications in Analysis and Mechanics, 2023 We study the reduction by symmetry for optimality conditions in optimal control problems of left-invariant affine multi-agent control systems, with partial symmetry breaking cost functions for continuous-time and discrete-time systems.

Exact Solutions of Newell-Whitehead-Segel Equations Using Symmetry Transformations
Journal of Function Spaces, 2021 In this article, Lie and discrete symmetry transformation groups of linear and nonlinear Newell-Whitehead-Segel (NWS) equations are obtained. By using these symmetry transformation groups, several group invariant solutions of considered NWS equations ...

Evolution of discrete symmetries
Physical Review E, 2023 Symmetries are known to dictate important physical properties and can be used as a design principle in particular in wave physics, including wave structures and the resulting propagation dynamics. Local symmetries, in the sense of a symmetry that holds only in a finite domain of space, can be either the result of a self-organization process or a ...

METHOD FOR ASSESSING THE SYMMETRY OF OBJECTS ON DIGITAL BINARY IMAGES BASED ON FOURIER DESCRIPTOR [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2019 In this paper we solve the problem of finding the symmetry axis of the object in a digital binary image. A new axial symmetry criterion is formulated for a connected discrete object.

Lagrangian reduction of discrete mechanical systems by stages [PDF]
, 2015 In this work we introduce a category of discrete Lagrange--Poincare systems LP_d and study some of its properties. In particular, we show that the discrete mechanical systems and the discrete mechanical systems obtained by the Lagrangian reduction of ...

Natural R-Parity, \mu-term, and Fermion Mass Hierarchy From Discrete Gauge Symmetries [PDF]
, 2002 In the minimal supersymmetric Standard Model with seesaw neutrino masses we show how R-parity can emerge naturally as a discrete gauge symmetry. The same discrete symmetry explains the smallness of the \mu-term (the Higgsino mass parameter) via the ...

Gauge origin of discrete flavor symmetries in heterotic orbifolds
Physics Letters B, 2014 We show that non-Abelian discrete symmetries in orbifold string models have a gauge origin. This can be understood when looking at the vicinity of a symmetry enhanced point in moduli space.

BMC Sports Science, Medicine and Rehabilitation, 2020 Background Symmetry during lifting is considered critical for allowing balanced power production and avoidance of injury. This investigation assessed the influence of elevating the heels on bilateral lower limb symmetry during loaded (50% of body weight)
