\curlyeqprec and \curlyeqsucc in LaTeX

In LaTeX, the \curlyeqprec and \curlyeqsucc commands are used to typeset curly "precedes or is equivalent to" and "succeeds or is equivalent to" symbols, respectively. These symbols are often used in mathematical logic or formal language theory to represent a weaker form of "precedes" or "succeeds" relation.

Syntax

The syntax of the \curlyeqprec and \curlyeqsucc commands is as follows:

\curlyeqprec[y-offset]{symbol}
\curlyeqsucc[y-offset]{symbol}

• The y-offset is an optional argument that allows adjusting the vertical position of the symbol (default is 0).
• The symbol argument specifies the symbol to be placed above the curly arrow.

Example Usage

Here's an example of how you can use the \curlyeqprec and \curlyeqsucc commands in LaTeX:

Let A, B, and C be sets such that A \curlyeqprec[0.5ex]{\cup} B \curlyeqsucc C.

This will generate the following output:

Let A, B, and C be sets such that A \curlyeqprec[0.5ex]{\cup} B \curlyeqsucc C.

In this example, \cup is the symbol placed above the curly arrow.

Tips and Tricks

• If you want to use a different symbol or combine multiple symbols, you can create a new command using \newcommand. For example:

\newcommand{\myarrow}{\curlyeqprec[0.5ex]{\diamond}}

• You can adjust the vertical position of the symbol by specifying a negative or positive value for y-offset. For example:

A \curlyeqsucc[-0.5ex]{\subseteq} B

This will shift the symbol down by 0.5ex.

Summary

The \curlyeqprec and \curlyeqsucc commands in LaTeX allow programmers to typeset curly "precedes or is equivalent to" and "succeeds or is equivalent to" symbols. These symbols can be used in various mathematical and logical contexts. Remember to enclose your code snippets in appropriate LaTeX markup when using these commands.
