	Das Verh{\"a}ltnis von Mathematik und Architektur ist ein spannungsreiches Wechselspiel von Inspiration und Emanzipation, Notwendigkeit und gestalterischer Freiheit, Formenvielfalt und Beschr{\"a}nkung auf das Wesentliche. W{\"a}hrend es in der Mathematik die M{\"o}glichkeit gibt, Strukturen losgel{\"o}st von materiellen Beschr{\"a}nkungen zu studieren, ist die Architektur dazu "verdammt" umsetzbar sein zu m{\"u}ssen. Der Mathematik wird dadurch in der Architektur eine doppelte Rolle zuteil. Einerseits ist die Mathematik als Grundlage von Baustatik, Materialphysik und r{\"a}umlicher Formgebung oftmals notwendiger Pr{\"u}fstein der Umsetzbarkeit. Dabei erm{\"o}glichen heute neue mathematische Techniken, insbesondere unter der Einbeziehung von Computern, auch die Umsetzung von neuen Geb{\"a}udekonzepten.</p>
