報(bào)告內(nèi)容簡(jiǎn)介：
We have introduced lightcone framed surfaces and lightcone framed curves as mixed type surfaces and curves with singular points, respectively. A more general notion of mixed type surfaces with singular points, called generalised lightcone framed surfaces, is introduced in this talk. The notion of generalised lightcone framed surfaces includes not only the notion of lightcone framed surfaces, but also the notion of one-parameter families of lightcone framed curves at least locally.
