Weak Dissipative solutions to a free-boundary problem for finitely extensible bead-spring chain molecules: variable viscosity coefficients
Donatella Donatelli, Tessa Thorsen, Konstantina Trivisa
We investigate the global existence of weak solutions to a free boundary problem governing the evolution of finitely extensible bead-spring chains in dilute polymers. The free boun…
On a free boundary problem for finitely extensible bead-spring chain molecules in dilute polymers
Donatella Donatelli, Konstantina Trivisa
We investigate the global existence of weak solutions to a free boundary problem governing the evolution of finitely extensible bead-spring chains in dilute polymers. We construct…
On the vanishing viscosity approximation of a nonlinear model for tumor growth
Donatella Donatelli, Konstantina Trivisa
We investigate the dynamics of a nonlinear system modeling tumor growth with drug application. The tumor is viewed as a mixture consisting of proliferating, quiescent and dead cell…
On a free boundary problem for polymeric fluids: Global existence of weak solutions
Donatella Donatelli, Konstantina Trivisa
We investigate the stability and global existence of weak solutions to a free boundary problem governing the evolution of polymeric fluids. We construct weak solutions of the two-p…
