A finite element method for exterior interface problems
International Journal of Mathematics and Mathematical Sciences, 1980 A procedure is given for the approximate solution of a class of two-dimensional diffraction problems. Here the usual inner boundary conditions are replaced by an inner region together with interface conditions.

Bulletin of the American Mathematical Society, 1991 Let X be a simply connected CW-complex of finite Lusternik-Schnirelmann category with finitely generated homology. In rational homotopy theory, the loop space homology of X is either relatively small (the elliptic case) or else very large (the hyperbolic case).

A Note on Gershgorin Disks in the Elliptic Plane
Journal of Mathematical Sciences and Modelling, 2021 In this study, we derive Gershgorin discs of elliptic complex matrices in the elliptic plane. Also, we investigate the location of the zeros of an elliptic complex valued polynomial with the help of Gershgorin discs of elliptic complex matrices.

Wide-Passband Dual-Polarized Elliptic Frequency Selective Surface
IEEE Access, 2019 The design of wide-passband dual-polarized elliptic frequency selective structures (FSSs) is proposed in this paper. The unit cell of the proposed structure is comprised of an array of cascaded square-patch resonators with a coupling layer consisting of ...

Multi-dimensional Morse Index Theorems and a symplectic view of elliptic boundary value problems [PDF]
, 2011 Morse Index Theorems for elliptic boundary value problems in multi-dimensions are proved under various boundary conditions. The theorems work for star-shaped domains and are based on a new idea of measuring the "oscillation" of the trace of the set of ...

Design and Synthesis of Quasi Dual-mode, Elliptic Coaxial Filter [PDF]
Radioengineering, 2015 This article introduces the design of a novel quasi dual-mode, elliptic coaxial filter. The transfer function is mapped to a generalized Chebyshev prototype with symmetrically located transmission zeros (TZs) where the coupling values are extracted ...

Weighted $L^p$ estimates for the elliptic Schrödinger operator
Electronic Journal of Qualitative Theory of Differential Equations, 2014 In this paper we study weighted $L^p$ estimates for the elliptic Schrödinger operator $P=-\Delta +V(x) $ with non-negative potentials $V(x)$ on $\mathbb{R}^n~(n\geq 3)$ which belongs to certain reverse Hölder class.
