Preface: Dedicated to the memory of Zoltán Ésik (1951–2016)
which took place at the Universität Leipzig, Germany, from May 5–9, 2014.
Weighted Automata: Theory and Applications (WATA 2014)
In addition, 9 invited lectures were presented by
Colin de la Higuera (Nantes, France),
Jacques Sakarovitch (Paris, France).
Furthermore, 29 talks were selected as contributed communications.
Laurent Doyen (Cachan, France),
Zoltán Ésik (Szeged, Hungary),

Paul Gastin (Cachan, France),
Ricard Gavaldà (Barcelona, Spain),

James Worrell (Oxford, Great Britain).
This workshop was financially supported by the DFG Research Training Group “Quantitative Logics and Automata” and by the Research Academy Leipzig.
After the workshop, a call for papers for a special issue of Soft Computing on “Quantitative Models and Weighted Automata” was issued. There were 15 submissions, and following the standard refereeing procedure, we were pleased to finally accept the present 7 papers for this special issue.
On May 25, 2016, our friend, colleague and co-editor of this special issue Zoltán Ésik passed away in Reykjavik, Iceland. Zoltán Ésik, Hungary’s leading theoretical computer scientist, was a scientist of highest calibre. It is impossible to describe his many important achievements in a preface. For obituaries, we kindly refer the reader to a special issue of Acta Cybernetica, to the International Journal of Foundations of Computer Science, to the Journal of Automata, Languages and Combinatorics, to the Bulletin of the EATCS, and to the web page of Academia Europaea. Among many areas, Zoltán Ésik was very active in the field and supportive for the community of weighted automata, and we would like to dedicate this special issue to him.
