Twisted Segre products

Ji-Wei He, Kenta Ueyama

We introduce the notion of the twisted Segre product $A \circ_{ψ} B$ of $Z$ -graded algebras $A$ and $B$ with respect to a twisting map $ψ$ . It is proved that if $A$ and $B$ are…

Combinatorial classification of $(\pm 1)$ -skew projective spaces

Akihiro Higashitani, Kenta Ueyama

The noncommutative projective scheme $Pro j_{nc} S$ of a $(\pm 1)$ -skew polynomial algebra $S$ in $n$ variables is considered to be a $(\pm 1)$ -skew projecti…
