Global superconvergence for Maxwell's equations
In this paper, the global superconvergence is analysed on two schemes (a mixed finite element scheme and a finite element scheme) for Maxwell's equations in R3. Such a superco...

On fundamental domains of arithmetic Fuchsian groups
Let K be a totally real algebraic number field and O an order in a quaternion algebra A over K. Assume that the group O1 of units in O with reduced norm equal to 1 is embedded into...

The third largest prime divisor of an odd perfect number exceeds one hundred
Let (n) denote the sum of positive divisors of the natural number n. Such a number is said to be perfect if (n) = 2n. It is well known that a number is even and perfect if and only...

On the error term of symmetric Gauss-Lobatto quadrature formulae for analytic functions
Gauss-Lobatto quadrature formulae associated with symmetric weight functions are considered. The kernel of the remainder term for classes of analytic functions is investigated on e...

Conjugacy classes in finite permutation groups via homomorphic images
The lifting of results from factor groups to the full group is a standard technique for solvable groups. This paper shows how to utilize this approach in the case of non-solvable n...

New primitive t-nomials (t = 3, 5) over GF(2) whose degree is a Mersenne exponent
All primitive trinomials over GF (2) with degree 859433 (which is the 33rd Mersenne exponent) are presented. They are X859433 + X288477 + 1 and its reciprocal. Also two examples of...

A posteriori error estimates for upwind finite volume schemes for nonlinear conservation laws in multi dimensions
In this paper we shall derive a posteriori error estimates in the L1-norm for upwind finite volume schemes for the discretization of nonlinear conservation laws on unstructured gri...

Optimal approximation of stochastic differential equations by adaptive step-size control
We study the pathwise (strong) approximation of scalar stochastic differential equations with respect to the global error in the L2-norm. For equations with additive noise we estab...
