## Description

This symbol is defined in the core so it can be used as the name of an optional argument by multiple packages.

## Functions with optional argument named Jacobian :

• reesAlgebra(...,Jacobian=>...) (missing documentation)
• "reesIdeal(...,Jacobian=>...)" -- see reesIdeal -- Compute the defining ideal of the Rees Algebra
• "specialFiber(...,Jacobian=>...)" -- see specialFiber -- Special fiber of a blowup
• "specialFiberIdeal(...,Jacobian=>...)" -- see specialFiberIdeal -- Special fiber of a blowup

## For the programmer

The object Jacobian is .
