SIAM Journal on Numerical Analysis, Vol. 44, No. 2 (2006), pp. 865-878 (14 pages) Robust quasi-relative Galerkin discretization error estimates are derived for the ...
In this work, the notion of extended eigenvalues of a 2 × 2 lower triangular operator matrix has been researched. More precisely, the relations between the extended spectrum of a 2 × 2 lower ...
Elliptic operators play a central role in the analysis of partial differential equations, underpinning a wide range of phenomena from quantum mechanics to heat conduction. In particular, the study of ...
