Proceedings Twelfth International Conference on Non-Classical Logics. Theory and Applications
Non-Classical Logics. Theory and Applications (NCL) is an international conference aimed at presenting novel results and survey papers in the broad field of non-classical logics and their applications. The first two editions were held in Ł{ó}d{ź}, Poland, in September 2008 and 2009. Subsequent editions were organised in Toru{ń} (2010, 2012, 2015, 2018) and Ł{ó}d{ź} (2011, 2013, 2016, 2022, 2024). The tenth edition of the conference, organised by the University of Ł{ó}d{ź} in 2022, was the first to have its proceedings published in EPTCS. We are honoured and pleased to continue this practice and, for the third time, include all accepted long papers in an EPTCS volume. Furthermore, for the first time, we have also included all accepted extended abstracts in the volume.
