The effects of fear have been investigated on the stability of the system. Granular function derivative concept has been used to do fuzzy mathematics. For the first time, proper model analysis, positivity, bounds and uniform persistence are studied for our proposed model in fuzzy environment. The conditions of stability of all co-existing equilibrium points and Hopf bifurcation analysis have also been studied in fuzzy environment. Analytical results have been justified by numerical simulation with proper table and graphical presentation in crisp and fuzzy environment both. <\/jats:p>","DOI":"10.1142\/s1793005722500351","type":"journal-article","created":{"date-parts":[[2021,9,23]],"date-time":"2021-09-23T05:39:37Z","timestamp":1632375577000},"page":"715-745","source":"Crossref","is-referenced-by-count":0,"title":["Study of Fear Effect on Prey\u2013Predator Model with Ivlev-Type Functional Response in Fuzzy Environment"],"prefix":"10.1142","volume":"18","author":[{"given":"Soumya","family":"Das","sequence":"first","affiliation":[{"name":"Department of Mathematics, Indian Institute of Engineering, Science and Technology, Shibpur, B.
