\(T\)-coercivity and continuous Galerkin methods: application to transmission problems with sign changing coefficients
This paper deals with the reformulation of the standard well-posedness theory within the \(T\)-coercivity framework. The authors explain how one can use this approach to solve the exact solution. Also, these results are applied to the indefinite transmission problem set in \(H^1_0(\Omega)\).
