  • A note on ▫$J$▫-positive block operator matrices
    Kostenko, Aleksej Sergejevič, 1980-
    We study basic spectral properties of ▫$\mathcal{J}$▫-self-adjoint ▫$2 \times 2$▫ block operator matrices. Using the linear resolvent growth condition, we obtain simple necessary conditions for the ... regularity of the critical point ▫$\infty$▫. We apply our results to the linearized operator arising in the study of soliton type solutions to the nonlinear relativistic Ginzburg-Landau equation.
