MathML Script and Limit

Ce contenu n’est pas encore disponible dans votre langue.

This category contains the script and limit elements for MathML. These elements will allow you to achieve typical mathematical notations.

Multiscripts - <mmultiscripts> Element

The <mmultiscripts> element in MathML is used to specify multiple superscripts and subscripts for a single base element. It allows for more complex notation involving multiple indices or exponents, commonly found in mathematical expressions involving tensors, matrices, or other mathematical structures.

Syntax and Usage

The <mmultiscripts> element can contain various child elements to specify the base, prescripts, and postscripts. Here’s a basic structure:

<mmultiscripts>
    <mi>base</mi>
    <!-- Prescripts and postscripts go here -->
</mmultiscripts>

Within the <mmultiscripts> element, you can specify the base element using any valid MathML element (such as <mi>, <mo>, etc.). Additionally, you can include <mprescripts> and <msuperscript>, <msubscript>, and <mmultiscripts> elements to define prescripts (superscripts before the base), superscripts, and subscripts, respectively.

Example Usage

Here’s an example of using <mmultiscripts> to represent a tensor: Tiklabc

<math>
    <mmultiscripts>
        <mn>T<mn>       <!-- the base -->


        <mi>i</mi>      <!-- sub-script 1 -->
        <mrow></mrow>   <!-- represent absent scripts -->


        <mi>k</mi>      <!-- sub-script 2 -->
        <mi>l</mi>      <!-- super-script 2 -->


        <mprescripts />


        <mrow></mrow>   <!-- represent absent scripts -->
        <mi>a</mi>      <!-- pre-super-script 1 -->


        <mi>b</mi>      <!-- pre-sub-script 2 -->
        <mi>c</mi>      <!-- pre-super-script 2 -->
    </mmultiscript>
</math>

In this example, the <mmultiscripts> element is used to represent a tensor T with multiple subscripts and superscripts. The base element is represented by the <mi> element with the content T. The subscripts and superscripts are specified using the <mi> elements with the content i, k, and l. The <mprescripts> element is used to indicate that there are prescripts in this case.

Over - <mover> Element

The <mover> element in MathML is used to represent expressions with a single overscript. This could be a variable with a bar (commonly used to represent a vector), a variable with a tilde (often used to represent a complex conjugate), or any other expression with an overscript.

Syntax and Usage

The <mover> element has two child elements: the base and the overscript.

<mover>
    <!-- Base element -->
    <!-- Overscript element -->
</mover>

Here’s an example of how you might represent a vector v→ using the <mover> element:

<math>
    <mover>
        <mi>v</mi> <!-- Base element -->
        <mo>&rarr;</mo> <!-- Overscript element (a right arrow) -->
    </mover>
</math>

In this example, <mi>v</mi> represents the base element (the variable v), and <mo>&rarr;</mo> represents the overscript (a right arrow →). Together, they represent the vector v→.
