On Partitioning Colored Points
P. Kirchberger proved that, for a finite subset of such
that each point in is painted with one of two colors, if every or
fewer points in can be separated along the colors, then all the points in
can be separated along the colors. In this paper, we show a more colorful
theorem
Design of resonant microcavities: application to optical gyroscopes
We study theoretically and numerically the effect of rotation on resonant
frequencies of microcavities in a rotating frame of reference. Cavity rotation
causes the shifts of the resonant frequencies proportional to the rotation rate
if it is larger than a certain value. Below the value, a region of rotation
rate exists where there is no resulting the frequency shifts proportional to
the rotation rate. We show that designing cavity symmetry as () can eliminate this region.Comment: 10 page
