Discontinuous Galerkin methods were first proposed and analyzed in the early 1970s as a technique to numerically solve partial differential equations. In 1973 Reed and Hill introduced a DG method to solve the hyperbolic neutron transport equation. See more In applied mathematics, discontinuous Galerkin methods (DG methods) form a class of numerical methods for solving differential equations. They combine features of the finite element and the finite volume framework … See more A scalar elliptic equation is of the form $${\displaystyle {\begin{aligned}-\partial _{xx}u&=f(x)\quad {\text{for}}\quad x\in (a,b)\\u(x)&=g(x)\,\quad {\text{for}}\,\quad x=a,b\end{aligned}}}$$ This equation is the steady-state heat equation, where $${\displaystyle u}$$ is the temperature.
