Boundary Extensions for mappings between metric spaces

In this paper, we consider boundary extensions of two classes of mappings between metric measure spaces. These two mapping classes extend in particular the well-studied geometric mappings such as quasiregular mappings with integrable Jacobian determinant and mappings of exponentially integrable distortion with integrable Jacobian determinant. Our main results extend the corresponding results of Äkkinen and Guo [Ann. Mat. Pure. Appl. 2017] to the setting of metric measure spaces.

Boundary Regularity for an Even Order Elliptic System in the Critical Dimension

In this short note, we consider the Dirichlet problem associated to an even order elliptic system with antisymmetric first order potential. Given any continuous boundary data, we show that weak solutions are continuous up to boundary.

Statistical Characterization of Self-Assembled Colloidal Crystals by Single-Step Vertical Deposition

We have statistically characterized the self-assembly of multi-layer polystyrene colloidal crystals, using the technique of vertical deposition, with parameters chosen to produce thick layers of self-assembled crystals in one deposition step. In addition, using a lithographically directed self-assembly method, we have shown that the size of multi-layer, continuous crack-free domains in lithographically defined areas can be many times larger than in the surrounding areas. In a single deposition step, we have produced continuous colloidal crystal films of 260 nm diameter polystyrene spheres approximately 30 -- 40 layers thick, with a controllable lateral size of 80 -- 100 $\upmu$m without lithography, and as high as 250 $\upmu$m with the lithographic template.
