Prof. Edward Lorenz (the "father" of chaos) and "shrimps"

In his last paper, Prof. Edward N. Lorenz rediscovered "shrimps" in discrete-time systems (maps)
and, in an endnote, graciously aknowledged the priority of our work, published in PRL in 1993.
He then cited 4 of our earlier (1993-99) papers:
Edward N. Lorenz, Compound windows of the Hénon map, Physica D  237,   1689-1704 (2008)

For a survey about shrimps in maps and first results concerning ODEs (Duffing):
HI-RES color figs (7.9 Mb):   Structure of the parameter space of a ring cavity,
LO-RES B&W figs (0.7 Mb):  Structure of the parameter space of a ring cavity,
J.A.C. Gallas
Applied Physics B 60, S203-S213 (1995), Special Supplement of the Festschrift Herbert Walther.
