Various Nyquist polynomials and their spectral factorizations to obtain suitable finite impulse response (FIR) vestigial sideband (VSB) filters are summarized here. The filters of interest have transfer functions that are polynomials with complex coefficients which are symmetric, due to Lawton, and polynomials whose coefficients are conjugate symmetric or conjugate antisymmetric, which are also...
The conjugate gradient algorithm (CG) is an eeective tool for solving a system of linear equation with a positive deenite coeecient matrix. We show the reasons for a possible breakdown of the method when applied to a symmetric system with an indeenite coeecient matrix. Although in nite arithmetic a breakdown of the method occurs rather seldom, near breakdowns may slow down the speed of converge...
We consider symmetric positive definite systems of linear equations with multiple right-hand sides. The seed conjugate gradient method solves one right-hand side with the conjugate gradient method and simultaneously projects over the Krylov subspace thus developed for the other right-hand sides. Then the next system is solved and used to seed the remaining ones. Rounding error in the conjugate ...
2. The Freudenthal theorem for symmetric spaces Our primary interest is in the classical compact groups; nevertheless, it is essential for our method to consider the larger family of compact symmetric spaces. A compact homogeneous Riemannian manifold M is called symmetric if it admits an 'inverse operation', i.e. if M admits an isometry, keeping a point P e M fixed, and whose differential at P ...
Similar kinds of problems have often been object of investigation. For instance, in [5] Fitzpatrick, using the classification of finite simple groups, proved that if in a finite group G any two elements of the same order are conjugate, thenG is isomorphic with the symmetric group Sn, with n ∈ {1, 2, 3} (see also [4]). Then in [10] there is the classification of finite groups for which elements ...
In this paper, we introduce some classes of univalent harmonic functions with respect to the symmetric conjugate points by means subordination, analytic parts which are reciprocal starlike (or convex) functions. Further, combining graph function, discuss bound Bloch constant and norm pre-Schwarzian derivative for classes.
In this paper we consider the violation of supersymmetric equivalence among the R parity violating couplings λijk caused by widely split chiral supermultiplets. The calculations have been done for two specific models of supersymmetry breaking: a) heavy SQCD models and b) 2-1 models. We find that if λ′2jk ≈ g and λ′1jk ≈ e then the violation of SUSY equivalence is of the order of 5-6 % in heavy ...
We present results of a search for R-parity-violating decay of the neutralino chi;01, taken as the lightest supersymmetric particle, to a muon and two jets. The decay proceeds through a lepton-number violating coupling lambda(')(2jk) (j=1,2; k=1,2,3), with R-parity conservation in all other production and decay processes. In the absence of candidate events from 77.5+/-3.9 pb(-1) of data collect...
By introducing a new mechanism based on purely imaginary conjugate metamaterials (PICMs), we reveal that bidirectional negative refraction and planar focusing can be obtained using a pair of PICMs, which is a breakthrough to the unidirectional limit in parity time (PT) symmetric systems. Compared with PT symmetric systems that require two different kinds of materials, the proposed negative refr...
We will show that a statistical manifold $$(M, g, \nabla )$$ has constant curvature if and only it is projectively flat conjugate symmetric manifold, is, the affine connection $$\nabla $$ curvatures satisfies $$R=R^*$$ , where $$R^*$$ of dual ^*$$ . Moreover, we properly convex structures on compact induces $$-1$$ vice versa.
