Reschke at Springer for her help and guidance. While they all may have helped me
completing this book, it is obviously clear that any errors or omissions are my own.
On a more personal level, my deepest appreciation and friendship goes out to Helena
Nelding-Kosuge and Ryusuke Kosuge as well as to Yukiko and Naonori Kishi,
Nicola Künkel, Ian Kattein, Marzia Scopelliti, Leilei Zou, Yulia Zaika, Shadi
Sakran, Nina and Teemu Kirjonen, Peter and Maike Sellheim, Doris Sellheim,
Yukino Thompson and Konstantin Sellheim, Katharina Sellheim and Christian
Zimmer-Sellheim, Helena and Matti Seppänen, Anu and Mikko Kähkönen, Daniel
Claassen, Christina Witt, Ulf Scheel, Maria Mattelmäki and Yuky Ryang.
Last but not least, the love of my wife and children is a love only the happiest of
men can receive.
Thank you all.
