Mathematical environments

The env-math d.t.d. specifies which mathematical environments can be used inside text-mode. In other words, the environments should be used inside text-mode, but their bodies contain mathematical formulas or tables of mathematical formulas.

equation
A numbered equation.
equation*
An unnumbered equation.
eqnarray
An array of numbered equations (should not be used yet).
eqnarray*
An array of unnumbered equations.

Inside the eqnarray* environment, you can use the eqnumber tag in order to number the equation.

Warning 1. The numbering of equations inside tables is not yet as it should be. In particular, the eqnarray tag is equivalent to eqnarray* at the moment. Later on, when the eqnarray tag will be implemented correctly, you will also have a nonumber tag in order to suppress the number of an equation, and a style package for numbering equations at the left hand side.

Warning 2. There is no option for numbering equations at the left hand side available yet. Nevertheless, you may use the manual tag leqnumber for this. You also have a tag nextnumber which directly display the next number and increases the equation counter.

Warning 3. We do not encourage the use of the AMS-TeX environments align, gather and split. Nevertheless, they are available under the names align, gather, eqsplit together with their variants align*, gather* and eqsplit*. In the future, we plan to provide more powerful environments.
