✦ Synopsis
Discretization errors in the first-order FEM for rotationally symmetric scalar potential in electrostatic lenses are studied for the case of irregular meshes and in the vicinity of electrodes. The expression of these errors has been obtained with the help of MAPLE. It helps us to understand the error estimates of the potential and gives us guidelines for proper mesh generation.

## Abstract We consider the calculation of first‐order and second‐order atomic and molecular properties from approximate ground‐state wave‐functions by using variational procedures for solving the first‐ and second‐order perturbation equations. We evaluate the errors in the final results due to the
In this paper, we analyze a first-order time discretization scheme for a nonlinear geodynamo model and carry out the convergence analysis of this numerical scheme. It is concluded that our numerical scheme converges with first-order accuracy in the sense of L 2 -norm with respect to the velocity fie
We consider the original discontinuous Galerkin method for the first-order hyperbolic problems in d-dimensional space. We show that, when the method uses polynomials of degree k, the L 2 -error estimate is of order k + 1 provided the triangulation is made of rectangular elements satisfying certain c
The measurement of absolute quantities, such as fluorescence quantum yields, by laser photothermal spectroscopy requires the use of reference compounds in order to determine the relationship between the signal and the amount of thermal energy released. Care has to be taken to avoid errors which may
