DESCRIPTION:Speaker: Christiaan van de Ven\nhosted by Robert Seiringer\nAbs
tract: In this seminar I present a study on the dynamics of classical infi
nite particle systems describing harmonic oscillators interacting with arb
itrarily many neighbors on lattices\, as well on more general structures\;
and I show that this enables the construction of C*-dynamical systems. Th
is approach allows particles with varying masses\, varying frequencies\, i
rregularly placed lattice sites and varying interactions subject to a simp
le summability constraint. A key role is played by the commutative resolve
nt algebra\, which is a C*-algebra of bounded continuous functions on an i
nfinite dimensional vector space\, and in a strong sense the classical lim
it of the Buchholz-Grundling resolvent algebra\, which suggests that quant
um analogs of our results are likely to exist. For a general class of Hami
ltonian dynamics\, it is demonstrated that this algebra is time-stable\, a
nd admits a time-stable sub-algebra on which the dynamics is strongly cont
inuous\, therefore obtaining a C*-dynamical system. Joint work with van Nu
land (TU Delft)
