Recollectionsity. The fact is that I do not feel like an elder citizen and am still somewhat shy in the company of my betters. Nevertheless I have been a mathematician for over forty years and some recollections of my early experiences may therefore be of interest.

Some Embedding Theorems for Modular ClassesThese results were successively generalized in [2], [3] and [4], based on the notion of σ-absorbed resp. σ-absorbing families of sets. Here, we observe that the latter result may be extended by replacing families of sets by families of functionals.

Stephen P. Keeler,Thomas A. GrandineA theorem of J.R.Partington on the resolvent of hermitian operators ([11], Th.5) is extended to a wider class of operators and a related problem on the growth of subharmonic functions is discussed.

Educational Justice and DiversityIn this paper the investigation of invariant subspace lattices of c.-contractions, begun in [8] and [9], is continued. Special emphasis is put on the behaviour of hyperinvariant subspaces under quasi-similarity. Moreover, a negative answer is given to a problem of Sz.-Nagy and Foiaş.

Educational Justice and the Public SchoolFor the real plane endowed with a strictly convex and smooth norm the class of maximally accretive operators coincides with the class of m-accretive operators exactly when the norm generates an inner product.
