Picard groups of quasi-Frobenius algebras and a question on Frobenius strongly graded algebras

Our initial aim was to answer the question: does the Frobenius (symmetric) property transfers from a strongly graded algebra to its homogeneous component of trivial degree? Related to it, we investigate invertible bimodules and the Picard group of a finite dimensional quasi-Frobenius algebra \(R\)....
