WebApr 16, 2014 · Based on the above analysis, we can see that the dynamics of B-T bifurcation can broadly fall into three types between different regions and curves: unstable virus equilibrium, no virus equilibrium, and no limit cycle; stable virus equilibrium; stable virus equilibrium and unstable limit cycle. WebThe codimension-2 bifurcation point, Bogdanov-Takens (BT) bifurcation, which is related to codimension-1 bi- furcations such as the SN bifurcation, homoclinic orbit (Hom) bifurcation, and Hopf bifurcation, is suggested to be related to switch between type I and II excitabil- ities. In some Refs.
Slow–fast Bogdanov–Takens bifurcations - ScienceDirect
WebAug 28, 2024 · It is proposed that the existence of Bogdanov–Takens (BT) bifurcation yields the bIfurcation of homoclinic loops, which provides a new mechanism for generating disease recurrence, for example, the relapse–remission, viral blip cycles in HIV infection.

WebApr 12, 2024 · The Hopf bifurcation vanishes at a Bogdanov-Takens (BT) point, and a saddle-node separatrix loop (SNSL) gives raise to a SNIC branch (dark blue line). Therefore, for most values of ϵ, gamma activity arises through a infinite-period (SNIC) bifurcation. Also, an increase of the coupling causes the region of bistability between the oscillatory ... crm meccanica

WebWe have also shown the occurrence of Bogdanov-Takens (BT) bifurcation using the Normal form. To set up a new hospital bed takes time, and so we have also analyzed our proposed model by incorporating time delay in the increment of newly created hospital beds. WebApr 10, 2024 · Nonlinear evolution equations (NLEEs) are extensively used to establish the elementary propositions of natural circumstances. In this work, we study the Konopelchenko–Dubrovsky (KD) equation which depicts non-linear waves in mathematical physics with weak dispersion. The considered model is investigated using the … WebThe bifurcation trees of period-1 to period-8 motions and period-3 to period-12 motions of FHN neuron are presented through the implicit discrete mapping method, and the stable and unstable orbits, which cannot study through the traditional numerical method, are calculated. ...
