Solution of n-phase ℝ-linear conjugation problem [PDF]

open access: yesRussian Mathematics, 2011
We consider the problem of the distribution of power fields of various physical nature in a piecewise homogeneous planar medium consisting of several homogeneous components separated by branches of confocal hyperbolas.

The linearization of equations and the conjugate factors

2013 10th International Computer Conference on Wavelet Active Media Technology and Information Processing (ICCWAMTIP), 2013
The linearization of the differential equations is always the important work in the study of partial differential equations. In this paper, a necessary and sufficient condition is established for the existence of a 1-1 transformation of a system of nonlinear differential equations to a system of linear equations is shown with some examples including ...

Cross‐Conjugation vs. Linear Conjugation in Donor–Bridge–Acceptor Nitrophenol Chromophores

European Journal of Organic Chemistry, 2014
AbstractThe influence of cross‐conjugation vs. linear conjugation on the electronic communication between donor and acceptor groups in phenol(ate)–bridge–nitrobenzene chromophores was investigated by solution and gas‐phase absorption spectroscopy, fluorescence spectroscopy, and quantum chemical calculations. The compounds studied include, among others,

Electrons-in-a-box model for conjugation in linear carbanions

International Journal of Quantum Chemistry, 1998
Solving the constrained Hartree–Fock equation and using the method of the energy component analysis, we have determined the fundamental factor which causes the electrons at the negative center of conjugated carbanion to delocalize over the whole system.

Linear Conjugate Gradient Algorithm

2020
The linear conjugate gradient algorithm is dedicated to minimizing convex quadratic functions (or solving linear algebraic systems of equations with positive definite matrices). This algorithm was introduced by Hestenes and Stiefel (1952).

Linear conjugate boundary value problems

Complex Variables, Theory and Application: An International Journal, 1996
The linear conjugate boundary value problems are studied in this paper. We obtained some kinds of contractive mapping by means of meromorphic approximatioa Using these maps we discuss the solvable conditions and the number of its solutions on these problems. We give the representations of its solutions, when there exist solutions to these problems.
