defined the [[signature defect]] of the boundary of a manifold as the [[eta invariant]], the value as &amp;#039;&amp;#039;s&amp;#039;&amp;#039;=0 of their eta function, and used this to show that Hirzebruch&amp;#039;s signature defect of a cusp of a [[Hilbert modular surface]] can be expressed in terms of the value at &amp;#039;&amp;#039;s&amp;#039;&amp;#039;=0 or 1 of a Shimizu L-function.&lt;br /&gt;
&lt;br /&gt;
==Definition==&lt;br /&gt;
&lt;br /&gt;
Suppose that &amp;#039;&amp;#039;K&amp;#039;&amp;#039; is a totally real algebraic number field, &amp;#039;&amp;#039;M&amp;#039;&amp;#039; is a lattice in the field, and &amp;#039;&amp;#039;V&amp;#039;&amp;#039; is a subgroup of maximal rank of the group of totally positive units preserving the lattice. The Shimazu L-series is given by&lt;br /&gt;
:&amp;lt;math&amp;gt;L(M,V,s) = \sum_{\mu\in \{M-0\}/V} \frac{\operatorname{sign} N(\mu)}{|N(\mu)|^s}&amp;lt;/math&amp;gt;&lt;br /&gt;
