Front propagation in a double degenerate equation with delay
Advances in Nonlinear Analysis, 2023 The current article is concerned with the traveling fronts for a class of double degenerate equations with delay. We first show that the traveling fronts decay algebraically at one end, while those may decay exponentially or algebraically at the other ...

Travelling waves due to negative plant-soil feedbacks in a model including tree life-stages
bioRxiv, 2023 The emergence and maintenance of tree species diversity in tropical forests is commonly attributed to the Janzen-Connell (JC) hypothesis, which states that growth of seedlings is suppressed in the proximity of conspecific adult trees.
