text: We study the hydrodynamic and hydrostatic limits of the one-dimensional open
symmetric inclusion process with slow boundary. Depending on the value of the
parameter tuning the interaction rate of the bulk of the system with the boundary,
we obtain a linear heat equation with either Dirichlet, Robin or Neumann boundary
conditions as hydrodynamic equation. In our approach, we combine duality and first-second
class particle techniques to reduce the scaling limit of the inclusion process
to the limiting behavior of a single, non-interacting, particle.

text: We consider symmetric partial exclusion and inclusion processes in a general
graph in contact with reservoirs, where we allow both for edge disorder and well-chosen
site disorder. We extend the classical dualities to this context and then we derive
new orthogonal polynomial dualities. From the classical dualities, we derive the
uniqueness of the non-equilibrium steady state and obtain correlation inequalities.
Starting from the orthogonal polynomial dualities, we show universal properties
of n-point correlation functions in the non-equilibrium steady state for systems
with at most two different reservoir parameters, such as a chain with reservoirs
at left and right ends.

sur un graphe général en contact avec des réservoirs. Nous autorisons la présence
de inhomogenéités sur les arrêts ainsi que sur les sommets du graph. Nous généralisons
les “dualités classiques” dans ce contexte et nous démontrons des nouvelles dualités

text: Motivated by the recent preprint [\emph{arXiv:2004.08412}] by Ayala, Carinci,
and Redig, we first provide a general framework for the study of scaling limits
of higher-order fields. Then, by considering the same class of infinite interacting
particle systems as in [\emph{arXiv:2004.08412}], namely symmetric simple exclusion
and inclusion processes in the d-dimensional Euclidean lattice, we prove the hydrodynamic
limit, and convergence for the equilibrium fluctuations, of higher-order fields.
In particular, the limit fields exhibit a tensor structure. Our fluctuation result
differs from that in [\emph{arXiv:2004.08412}], since we considered-dimensional
Euclidean lattice, we prove the hydrodynamic limit, and convergence for the equilibrium
fluctuations, of higher-order fields. In particular, the limit fields exhibit
a tensor structure. Our fluctuation result differs from that in [\emph{arXiv:2004.08412}],
since we consider a different notion of higher-order fluctuation fields.

text: In this paper, we introduce a random environment for the exclusion process
in obtained by assigning a maximal occupancy to each site. This maximal occupancy
is allowed to randomly vary among sites, and partial exclusion occurs. Under the
assumption of ergodicity under translation and uniform ellipticity of the environment,
we derive a quenched hydrodynamic limit in path space by strengthening the mild
solution approach initiated in Nagy (2002) and Faggionato (2007). To this purpose,
we prove, employing the technology developed for the random conductance model,
a homogenization result in the form of an arbitrary starting point quenched invariance
principle for a single particle in the same environment, which is a result of
independent interest. The self-duality property of the partial exclusion process
allows us to transfer this homogenization result to the particle system and, then,
apply the tightness criterion in Redig et al. (2020).

text: We consider the symmetric simple exclusion process in Zd with quenched bounded
dynamic random conductances and prove its hydrodynamic limit in path space. The
main tool is the connection, due to the self-duality of the process, between the
invariance principle for single particles starting from all points and the macroscopic
behavior of the density field. While the hydrodynamic limit at fixed macroscopic
times is obtained via a generalization to the time-inhomogeneous context of the
strategy introduced in [41], in order to prove tightness for the sequence of empirical
density fields we develop a new criterion based on the notion of uniform conditional
stochastic continuity, following [50]. In conclusion, we show that uniform elliptic
dynamic conductances provide an example of environments in which the so-called
arbitrary starting point invariance principle may be derived from the invariance
principle of a single particle starting from the origin. Therefore, our hydrodynamics
result applies to the examples of quenched environments considered in, e.g., [1],
[3], [6] in combination with the hypothesis of uniform ellipticity.
