Embedding a quantum nonsingular quadric in a quantum \(\mathbb{P}^3\)
The paper deals with the classification of a certain class of quadratic regular algebras of global dimension four, i.e. those having the same Hilbert series as the polynomial ring in four indeterminates, and which map onto a twisted homogeneous coordinate ring of a nonsingular quadric in \(\mathbb{P}^3\) via a graded morphism (of degree zero).
