# On the history of the Hopf problem

@article{Agricola2017OnTH, title={On the history of the Hopf problem}, author={Ilka Agricola and Giovanni Bazzoni and Oliver Goertsches and Panagiotis Konstantis and Sonke Rollenske}, journal={arXiv: History and Overview}, year={2017} }

This short note serves as a historical introduction to the Hopf problem: "Does there exist a complex structure on $S^6$?"
This unsolved mathematical question was the subject of the Conference "MAM 1 $-$ (Non-)Existence of Complex Structures on $S^6$", which took place at Philipps-Universit\"at Marburg, Germany, between March 27th and March 30th, 2017.
