Algebraic Geometry

For version 2.8 the algebraic geometry suite has been completely re-engineered. Most functionality has been moved into the kernel and idiosyncrasies of the first geometry implementation have been removed. The major categories that have been added or enhanced are

• Schemes
• Rational scrolls
• Zero-dimensional schemes
• Algebraic curves
• Divisor groups of plane curves
• Rational curves
• Elliptic curves
• Hyperelliptic curves
