... in Section 3, where for different values of λ, we study positive, pseudo dead core, and dead core solutions of problem 1.9a - 1.9b and positive solutions of problem 1.5a - 1.5b Analytical Results ... unique dead core solution and a unique positive solution of problem 1.9a - 1.9b iii For each λ ∈ 4/9 3/ 3α 4β 3/2 , M , there exist a unique dead core solution and exactly two positive solutions of ... and 1.6a holds for t ∈ ρ, The interval 0, ρ is called the dead core of u If ρ 0, then u is called a pseudo dead core solution of problem 1.6a - 1.6b The aim of this paper is twofold First of...
