A degenerate parabolic equation modelling the spread of an epidemic [PDF]
Annali di Matematica Pura ed Applicata, 1986 We consider the Cauchy problem for a degenerate parabolic equation, not in divergence form, representing the diffusive approximation of a model for the spread of an epidemic in a closed population without remotion. We prove existence and uniqueness of the weak solution, defined in a suitable way, and some qualitative properties.

Regularity results for degenerate parabolic equations with Lm data
Complex Variables and Elliptic Equations, 2022In this paper, we study the existence and regularity results for some nonlinear parabolic equations with degenerate coercivity, when the right-hand side is in with m>1.

A System of Degenerate Parabolic Equations
SIAM Journal on Mathematical Analysis, 1990The system of two nonlinear equations which arises in plasma physics is considered. The equations are of degenerate parabolic type. The global existence theorem for the Cauchy problem is proved. The proof is based on the Lagrangian transformation, thus using a particular structure of the system.

Numerical Methods for Partial Differential Equations, 2020
In this research, a new high‐order WENO method for solving 1D, 2D and 3D non‐linear degenerate parabolic equations which may contain discontinuous solutions has been designed. The new scheme is constructed by three polynomials of varying degrees.

Nonuniqueness of solutions of a degenerate parabolic equation
Annali di Matematica Pura ed Applicata (1923 -), 1992We give some results about nonuniqueness of the solutions of the Cauchy problem for a class of nonlinear degenerate parabolic equations arising in several applications in biology and physics. This phenomenon is a truly nonlinear one and occurs because of the degeneracy of the equation at the points where u=0.
