More recent publications on quaternionic quantum mechanics
     and noncommutative dynamics are:

  1. "Generalized Quantum Dynamics as Pre-Quantum Mechanics" (with Andrew C. Millard), IASSNS-HEP-95/66;available from the bulletin board as hep-th/9508076; Nucl. Phys. B 473, 199 (1996) Shows that the canonical quantization rules can be deduced from generalized quantum dynamics if one assumes there is a regime where statistical mechanical methods can be applied. Extends the discussion of Secs. 13.5-7 of the book. A related paper (with L. Horwitz), "Microcanonical Ensemble and Algebra of Conserved Generators for Generalized Quantum Dynamics ", is on the bulletin board as hep-th/9606023; J. Math. Phys. 37, 5429 (1996) For an update on the paper with Millard, see S. Adler and A. Kempf, "Corrections to the Emergent Canonical Commutation Relations Arising in the Statistical Mechanics of Matrix Models", hep-th/9709106, J. Math. Phys. 39, 5083 (1998). Gauge fixing is discussed in S. Adler, "Gauge fixing in the partition function for generalized quantum dynamics", J. Math. Phys. 39, 1723 (1998). The extension of rigid supersymmetry to GQD is given in S. Adler, "Poincar\'e supersymmetry representations over trace class non-commutative graded operator algebras", Nucl. Phys. B 499, 569 (1997). See also ``The Matrix Model for M Theory as an Exemplar of Trace (or Generalized Quantum) Dynamics'' , Phys. Lett. B407, 229 (1997). Possible relevance of GQD to the cosmological constant problem is discussed in "A Strategy for a Vanishing Cosmological Constant in the Presence of Scale Invariance Breaking", Gen. Rel. and Grav. 29, 1357 (1997). For a pedagogical account of Andrew Millard's thesis, and the thesis text, see Millard's home page http://www-wilson.ucsd.edu/~acm/papers/index.html ****NEW**** The draft of a book on the trace dynamics program has been put on the bulletin board: ``Statistical Dynamics of Global Unitary Invariant Matrix Models as Pre-Quantum Mechanics'', hep-th/0206120. This has been expanded and published as a book by Cambridge University Press in Sept, 2004, with the title " Quantum Theory as an Emergent Phenomenon" A current list of errata and addenda for this book is as follows:
    • After the book went to press, I learned from Pierre Hohenberg of a review by Tony Leggett that is relevant to the discussion of Chapter 6: "Testing the limits of quantum mechanics: motivation, state of play, prospect", A. J. Leggett, J. Phys.: Conden. Matter 14, R415 (2002).
    • On pages 164 and 165, in the second lines of Eqs. (6.10b) and (6.10d), a factor of dt was omitted. This factor does appear in the first lines of the two equations. In the sentence immediately following Eq. (6.10d), ``spatially correlated'' should read ``spatially localized''.

  2. "Projective Group Representations in Quaternionic Hilbert Space", IASSNS-HEP-96/02; available from the bulletin board as hep-th/9601047; J. Math.Phys. 37, 2352 (1996). This paper discusses the consequences of the associativity condition for projective group representations in quaternionic Hilbert space, and extends the discussion given in Sec. 4.3 of the book. A later paper by Andrew C. Millard and Terry Tao, Princeton University, ``On the Structure of Projective Group Representations in Quaternionic Hilbert Space'', proves a structure theorem for quaternionic projective representations, and shows that multi-central implies central in the connected case; this paper will also appear in J. Math. Phys. A subsequent paper by S. L. Adler, "Response to the Comment by G. Emch on Projective Group Representations in Quaternionic Hilbert Space " is available from the bulletin board as hep-th/9609012; J. Math. Phys. 37, 6586, 1996; see also the paper with G. Emch, "A rejoinder on quaterionic projective representations", J. Math. Phys. 38, 4758 (1997). A paper " Coherent States in Quaternionic Quantum Mechanics ", by S. L. Adler and A. C. Millard, appears in J. Math. Phys. 38, 2117 (1997). Also, a paper "Nonadiabatic Geometric Phase in Quaternionic Hilbert Space " by S. L. Adler and J. Anandan, has been submitted to the Foundations of Physics issue dedicated to the 60th birthday of Prof. Larry Horwitz.
