Simson's Brauer-Thrall 3 conjecture for finite-dimensional algebras

Let AA be a finite-dimensional algebra that is not of finite type, and let λ\lambda be an infinite cardinality. An AA-module MM is indecomposable if it cannot be expressed as a direct sum of two nonzero submodules.

Simson's Brauer-Thrall 3 conjecture. For any infinite cardinality λ\lambda, there is an indecomposable AA-module MM of dimension

dim(M)λ.\dim(M)\geq \lambda.

This is presented as a question concerning the existence of arbitrarily large indecomposable modules over finite-dimensional algebras that are not of finite type. The supplied status is unknown.
