EQUIVARIANT HOMOTOPY EQUIVALENCES AND A FORGETFUL MAP
Tsukiyama, Kouzou Korean Mathematical Society 1999 대한수학회보 Vol.36 No.4
We consider the forgetful map from the group of equivariant self equivalences to the group of non-equivariant self equivalences. A sufficient condition for this forgetful map being a monomorphism is obtained. Several examples are given.

In the design of column driver circuit of liquid crystal displays, a sampling circuit must be designed so that the pixel voltage of a pixel is as close to an input video voltage as possible in various conditions. In this paper, we propose a design method of finding optimal combinations of a sampling switch size and a sampling pulse waveform, which attains this objective. Moreover, in order to optimize both buffer and sampling circuits, we propose a figure of suitability of each combination to the design of buffer circuit generating sampling pulses. We show an experimental result which indicates that the proposed method produced almost equal quality design in eleven times faster than the optimizer in SPICE.
