AB - <p style="text-align: justify;">We discuss a priori error estimates for a semidiscrete
piecewise linear finite volume element (FVE) approximation to a second
order wave equation in a two-dimensional convex polygonal domain. Since
the domain is convex polygonal, a special attention has been paid to
the limited regularity of the exact solution. Optimal error estimates in $L^2$, $H^1$ norms and quasi-optimal estimates in $L^∞$ norm are
discussed without quadrature and also with numerical quadrature.
Numerical results confirm the theoretical order of convergence.</p>
