## Abstract A second‐order finite difference scheme for mixed boundary value problems is presented. This scheme does not require the tangential derivative of the Neumann datum. It is designed for applications in which the Neumann condition is available only in discretized form. The second‐order con

Abstract
We suggest a flexible way to study the self‐similar interface of two different fractals. In contrast to previous methods the participating energies are modified in the neighborhood of the intersection of the fractals. In the example of the Vicsek snowflake and the 3‐gasket, a variant of the Sierpinski gasket, we calculate the admissible transition constants via the “Short‐cut Test”. The resulting range of values is reinterpreted in terms of traces of Lipschitz spaces on the intersection. This allows us to describe the interface effects of different transition constants and indicates the techniques necessary to generalize the present interface results.

## Abstract A high‐directivity microstrip array using multilevel elements based on fractal geometry is theoretically compared with an array using circular patches. Within the same electrical area, the same directivity can be obtained. However, the number of elements for the fractal‐based array is 2
## Abstract The three dimensional interface problem is considered with the homogeneous Lamé system in an unbounded exterior domain and some quasistatic nonlinear elastic material behavior in a bounded interior Lipschitz domain. The nonlinear material is of the Mooney‐Rivlin type of polyconvex mater
To avoid the difficulty of overlapping material near the crack tips, the tips of the crack are assumed to be closed (the Comninou model). The exact series solution to the problem of the interface crack under combined loading is complicated, and it is difficult to take advantage of the smallness of t
We prove a Carleman estimate for hyperbolic equations with variable principal parts and present applications to the unique continuation and an inverse problem. Our Carleman estimate covers cases which the existing Carleman estimates do not treat.
