 Creating a team that implies a wrap-around sequence &
 If the triplet provided to \FUNC{shmem\_team\_split\_strided} implies a
 wrap-around sequence, the input is considered invalid and the behavior is
 undefined.
 In other words, when $stride$ is nonzero, a newly created team must only
 include \acp{PE} whose subsequent parent \ac{PE} values are either all
-increasing (for positive $stride$) or all decreasing (for negative
-$stride$).
+increasing (for positive \VAR{stride}) or all decreasing (for negative
+\VAR{stride}).
 That is, \textit{wrap-around} with respect to the parent team's \ac{PE} values
 is not permitted.
 For example, given a parent team with a size of 8 \acp{PE}, a call to
 \FUNC{shmem\_team\_split\_strided} with the following arguments would
-be invalid: $start$ equal to 3, $stride$ equal to 3, and $size$ equal to 3. \tabularnewline
