Hierarchical Control for the Semilinear Parabolic Equations With Interior Degeneracy
Journal of Mathematical Analysis and ApplicationsThis paper concerns with the hierarchical control of the semilinear parabolic equations with interior degeneracy. By a Stackelberg-Nash strategy, we consider the linear and semilinear system with one leader and two followers. First, for any given leader, we analyze a Nash equilibrium corresponding to a bi-objective optimal control problem.

Degeneracy Effects on Photoionization in the Solar Interior
Journal of Physics B: Atomic, Molecular and Optical Physics, 1993The rate of production of solar neutrinos is very sensitive to small variations in the radiative opacity of the material at the centre of the Sun. Relatively small changes to the predicted values of the solar radiative opacity are therefore of particular relevance to the solar neutrino problem.

Degeneracy Degrees of Constraint Collections
Mathematical Methods of Operations Research, 2003 This paper presents an unifying approach to the theory of degeneracy of basic feasible solutions, vertices, faces, and all subsets of polyhedra. It is a generalization of the usual concept of degeneracy defined for basic feasible solutions of an LP ...

Astronomy and AstrophysicsContext. With a new generation of observational instruments largely dedicated to exoplanets (i.e. JWST, ELTs, PLATO, and Ariel) providing atmospheric spectra and mass and radius measurements for large exoplanet populations, the planetary models used to understand the findings are being put to the test. Aims.

Abstract In this paper, we study boundary controllability for the linear extension problem of a wave equation with space-dependent coefficients and having an internal degeneracy. For this purpose, we mainly focus on the well-posedness and the boundary null controllability of a relaxed version of the original problem, namely, to some ...

We study an identification problem associated with a strongly degenerate parabolic evolution equation of the type $$\displaystyle{y_{t} -\mathit{Ay} = f(t,x),\quad (t,x) \in Q:= (0,T) \times (0,L)}$$ equipped with Dirichlet boundary conditions, where T > 0, L > 0, and f is in a suitable L 2 space.
