• openAccess   Exact solution to a multidimensional wave equation with delay 

      Jornet, Marc Elsevier (2021-06-15)
      This paper deals with a mixed problem for the wave equation with discrete delay τ>0, utt (t , x) = a 1 2 Δx u (t,x) + a 2 2 Δx u (t – τ , x) + b1u (t,x) + b2u (t−τ,x), t > τ,0 ≤ x ≤ l,with Dirichlet boundary conditions. ...
