報告題目:H(curl curl)-conforming and H(grad curl)-conforming finite elements---beyond Nedelec

報告摘要：In his two ground breaking papers (1980 and 1986), Nedelec proposed H(curl)-conforming and H(div)-conforming elements to solve second-order electromagnetic equations that contains the “curl” and “div” operators. It is more or less as the $H^1$-conforming elements (or $C^0$ elements) for second-order elliptic equations that contains the $(grad)^2$ operator. As is well known in the finite element method literature, in order to solve 4th-order elliptic equations such as the bi-harmonic equation, $H^2$-conforming elements (or $C^1$-elements) were developed. Recent years, there have been some research in solving electromagnetic equations which involve $curl^4$ operator and $(curl grad)^2$ operator. Hence, construction of H(curl curl)-conforming and H(grad curl)-conforming elements becomes necessary. In this work, we report some recent development in this direction.
