An Unconstrained Formulation of Some Constrained Partial Differential Equations and its Application to Finite Neuron Methods
Jiwei Jia, Young Ju Lee, Ruitong Shan
In this paper, we present a new framework how a PDE with constraints can be formulated into a sequence of PDEs with no constraints, whose solutions are convergent to the solution o…
