We define the osculating horosphere of the curve. We also define the horospherical surface of the curve whose singular points correspond to the locus of polar vectors of osculating horospheres of the curve. One of the main results is to give a generic classification of singularities of horospherical surface of curves.Departmental Bulletin Paperapplication/pdfhttp://hdl.handle.net/2115/69266info:doi/10.14943/83662https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/69266/1/pre516.pdfHokkaido University Preprint Series in Mathematics516192001-01-01engpublisher
