ABSTRACT
In this note, we show that a derived tubular algebra is strongly simply connected if and only if it contains no full convex subcategory which is hereditary of type A ˜ m https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9780429187759/559656af-5888-4439-a5d2-08d7a38d7161/content/inq_chapter3_21_1.tif"/> , and give several other characterisations of the strong simple connectedness of (derived) tubular algebras.
