chapter heading in the running head Each chapter should be preceded by an abstract (10–15 lines long) that summarizes the content. The abstract will appear online at www.SpringerLink.com and be available with unrestricted access. This allows unregistered users to read the abstract as a teaser for the complete chapter. As a general rule the abstracts will not appear in the printed version of your book unless it is the style of your particular book or that of the series to which your book belongs. Please use the 'starred' version of the abstract environment for typesetting the text of the online abstracts. Use the plain abstract if the abstract is also to appear in the printed version of the book. Each chapter should be preceded by an abstract (10–15 lines long) that summarizes the content.

Instead of simply listing headings of different levels we recommend to let every heading be followed by at least a short passage of text. Use the standard equation environment to typeset your equations, e.g. a\times b=c\;, a×b=c, however, for multiline equations we recommend to use the eqnarray environment In physics texts please activate the class option vecphys to depict your vectors in boldface-italic type - as is customary for a wide range of physical subjects. . a\times b & = & c\nonumber \\ \vec{a}\cdot\vec{b} & = & c\label{eq:01} a×b = c a → ⋅ b → = c
