Modeling and analysis in a prey–predator system with commercial harvesting and double time delays

作者:

Highlights:

• Both maturation delay for prey and gestation delay for predator are considered.

• Positivity of solutions and uniform persistence of system are investigated.

• Combined dynamic effects of double time delays and economic interest are studied.

• Existence and control for singularity induced bifurcation are investigated.

• Local stability analysis and properties of Hopf bifurcation are studied.
