Real sets

Dear Colleagues We are sorry to say that Examples 5.5 and 5.6 in our paper [Real sets, Tbilisi Mathematical Journal 10(3) (2017) 23--49] are not examples of series monoidal categories afterall. Our attempts to accommodate them are leading to interesting directions which will take awhile to finalise. For now, in a new arXiv version of ``Real Sets'', we have pointed out that those Examples, and the dependent Examples 5.12 and 5.13, are in error. Nothing else in the paper depends on those examples.
