Weeping Cherry sprawls back on the grass, watching Árvakr and Alsviðr pull the sun across the dome above the park. To her left, a waterfeature burbles and runs down to a small pond. Across the park, a game of frisbee is failing to happen, in the way that games on long summer days sometimes do. She thinks she's nearly cracked the dimensional boundary shear problem. She's supposed to be relaxing after her shift, but jotting down a few ideas won't hurt.
She rolls over and creates a writing pillow, desk, fineliner pen, and a pretty purple notebook. She taps the desk a few times, and then writes:
Boundary effects --> noninvertable tensor?
Stable if the dimensional boundary is inside a singularity -- inner wormhole prevents disconnection.
