%0 Journal Article %J Synthese %D 2009 %T Adaptive Logics using the Minimal Abnormality strategy are \$\textbackslashPi\^ 1\_1\$-complex %A Verdée, Peter %X

In this article complexity results for adaptive logics using the minimal abnormality strategy are presented. It is proven here that the consequence set of some recursive premise sets is Pi(1)(1)-complete. So, the complexity results in ( Horsten and Welch, Synthese 158: 41- 60, 2007) are mistaken for adaptive logics using the minimal abnormality strategy.
