In this paper, we propose some least-squares finite element procedures for linear and nonlinear parabolic equations based on first-order systems. By selecting the least-squares functional properly each proposed procedure can be split into two independent symmetric positive definite sub-procedures, o
## Abstract Timeβintegration methods for semidiscrete equations emanating from parabolic differential equations are analysed in the frequency domain. The discreteβtime transfer functions of three popular methods are derived, and subsequently the forced response characteristics of single modes are s
