      abstract     = {Ionic microgels are highly sensitive to changes in
                      environmental conditions. This allows for controlling their
                      size and effective interactions by adjusting the
                      temperature, solvent quality, degree of polymer
                      cross-linking, suspension ionic strength and particle
                      concentration.In this work, we study theoretically the
                      influence of the concentration-dependent de-swelling of
                      weakly-crosslinked ionic microgels on structural and dynamic
                      suspension properties. Our analysis is based on an effective
                      interaction potential for ionic microgels derived by Denton
                      [1], where we consistently introduce the de-swelling effect
                      using the Denton-Tang method to compute the equilibrium
                      microgel size [2]. Using the effective interaction
                      potential, we compute pair correlation functions and static
                      structure factors, which in turn are used as input for the
                      calculation of dynamic suspension properties. The latter
                      include hydrodynamic functions, collective diffusion
                      coefficients, and the low- and high-frequency viscosities.
                      We present and discuss results for the dependence of
                      structural and dynamic properties on salt and microgel
                      concentrations and on bare microgel charge. References[1] A.
