DESCRIPTION:The talk will be a survey of topological models fo
r elementary particles including the work of Lord
Kelvin\, Herbert Jehle\, Thomas Kephart\, Jack Avr
in\, Sundance Bilson-Thompson and recent work of t
he speaker with Sundance Bilson-Thompson and Jonat
han Hackett and work of the speaker on the Fibonac
ci model in quantum information theory. Lord Kelvi
n suggested that atoms (the elementary particles o
f his time) are knotted vortices in the luminifero
us aether. Jehle (much later on) suggested that el
emenary particles should be quantized knotted elec
tromagnetic flux. Kephart and Buiny suggest that c
losed loops of gluon field can be knotted particle
s -- knotted glueballs. Avrin notes that a three h
alf-twisted Mobius band could be like a proton com
posed of three quarks mutually bound. Sundance Bil
son-Thompson has a theory of framed three-braids t
hat is a topological version of preons. In this th
eory we can think of particles as topological defe
cts in networks of surfaces and some properties of
embedded surfaces may sort out the matter. In the
Fibonacci model for topological quantum computing
\, the system is generated by a braided anyonic ab
stract particle P that interacts with itself to pr
oduce itself (PP -----> P) or iteracts with itself
to produce a neutral particle (PP ------> 1). The
elementary particle P of the Fibonacci model is a
structure that can be seen as a logical particle\
, underlying all the mathematical structures that
we know. Since this talk surveys such a range of i
deas\, it will be up to the speaker to find a way
to summarize these diseparate views at the time of
the talk.\n
