|
||
|
|

|
||
|
|
% version 1.7: changed \let\@mkboth\markboth to
|

|
|
% \def\@mkboth{\protect\markboth} to make it more robust
|
||
|
|
% Dec 5, 1994:
|
||
|
|
% version 1.8: corrections for amsbook/amsart: define \@chapapp and (more
|
||
|
|
% importantly) use the \chapter/sectionmark definitions from ps@headings if
|
||
|
|
% they exist (which should be true for all standard classes).
|
||
|
|
% May 31, 1995:
|

|
|
% version 1.9: The proposed \renewcommand{\headrulewidth}{\iffloatpage...

||
|
|
% June 1, 1995:
|
||
|
|
% version 1.92: The sequence \pagestyle{fancyplain} \pagestyle{plain}
|
||
|
|
% \pagestyle{fancy} would erroneously select the plain version.
