Binary projective space

A study of a generalized projective scheme closely related to the binary projective space $\mathbf P^{(2)}=\operatorname{Proj}\mathbb F_0[t]$, where $t$ is a free binary variable, is started. In particular, the global sections of the structure sheaf on elements of certain affine covering are computed and the scheme point of the unary version are described. Bibl. – 4 titles.
