Finite element scheme achieves optimal error bounds for corotational heat flow
—
in MathematicsWhat the study found The study found optimal order discretization error bounds for a finite element approximation of the corotational harmonic map heat flow problem. The analysis applies to smooth solutions of the continuous problem. Why the authors say this matters The authors indicate that the method's key analytical tools help with discrete stability and…
