Analysis of the Hopf bifurcation for the family of angiogenesis models II: The case of two nonzero unequal delays

作者:

Highlights:

• We analyse the of family of models describing the angiogenesis process.

• We examine the existence of Hopf bifurcation for DDE system with two unequal delays.

• We analyze Hopf bifurcation type when one of delays is a bifurcation parameter.

• Our analysis covers the case of well-know Hahnfeldt et al. model with included delays.

• We extend the results from the previous work where only one delay is nonzero.
