# Simple transitive 2-representations via (co)algebra 1-morphisms

@article{Mackaay2016SimpleT2, title={Simple transitive 2-representations via (co)algebra 1-morphisms}, author={Marco Mackaay and Volodymyr Mazorchuk and Vanessa Miemietz and Daniel Tubbenhauer}, journal={Indiana University Mathematics Journal}, year={2016} }

For any fiat 2-category C, we show how its simple transitive 2-representations can be constructed using coalgebra 1-morphisms in the injective abelianization of C. Dually, we show that these can also be constructed using algebra 1-morphisms in the projective abelianization of C. We also extend Morita-Takeuchi theory to our setup and work out several examples explicitly.
