We consider the Cauchy problem for nonstationary 1D flow of a compressible viscous and heat-conducting micropolar fluid, assuming that it is in the thermodynamical sense perfect and polytropic. This problem has a unique generalized solution on R×0,T for each T>0. Supposing that the initial functions are small perturbations of the constants we derive a priori estimates for the solution independent of T, which we use in proving of the stabilization of the solution. 1. Introduction In this paper we consider the Cauchy problem for nonstationary 1D flow of a compressible viscous and heat-conducting micropolar fluid. It is assumed that the fluid is thermody- namically perfect and polytropic. The same model has been considered in 1, 2, where the global-in-time existence and uniqueness for the generalized solution of the problem on R×0,T,T>0, are proved. Using the results from 1, 3 we can also easily conclude that the mass density and temperature are strictly positive. Stabilization of the solution of the Cauchy problem for the classical fluid where microrotation is equal to zero has been considered in 4, 5.In4 was analyzed the H ¨ older continuous solution. In 5 is considered the special case of our problem. We use here some ideas of Kanel’ 4 andtheresultsfrom1, 5 as well. Assuming that the initial functions are small perturbations of the constants, we first derive a priori estimates for the solution independent of T. In the second part of the work we analyze the behavior of the solution as T →∞. In the last part we prove that the solution of our problem converges uniformly on R to a stationary one. 2 Boundary Value Problems The case of nonhomogeneous boundary conditions for velocity and microrotation which is called in gas dynamics “problem on piston” is considered in 6. 2. Statement of the Problem and the Main Result Let ρ, v, ω,andθ denote, respectively, t he mass density, velocity, microrotation velocity, and temperature of the fluid in the Lagrangean description. The problem which we consider has the formulation as follows 1: ∂ρ ∂t  ρ 2 ∂v ∂x  0, 2.1 ∂v ∂t  ∂ ∂x  ρ ∂v ∂x  − K ∂ ∂x  ρθ  , 2.2 ρ ∂ω ∂t  A  ρ ∂ ∂x  ρ ∂ω ∂x  − ω  , 2.3 ρ ∂θ ∂t  −Kρ 2 θ ∂v ∂x  ρ 2  ∂v ∂x  2  ρ 2  ∂ω ∂x  2  ω 2  Dρ ∂ ∂x  ρ ∂θ ∂x  2.4 in R × R  , where K, A,andD are positive constants.

A. CORR ˆ EA AND GIOVANY M. FIGUEIREDO Received 18 November 2005; Revised 11 April 2006; Accepted 18 April 2006 Dedicated to our dear friend and collaborator Professor Claudianor O. Alves We investigate the questions of existence of positive solution for the nonlocal problem −M(u 2 )Δu = f (λ,u)inΩ and u = 0on∂Ω,whereΩ is a bounded smooth domain of R N ,andM and f are continuous functions.

Introduction In this paper, we study some questions related to the existence of positive solution for the nonlocal elliptic problem − M   u 2  Δu = f (λ, u)inΩ, u = 0on∂Ω, (P) λ where Ω is a bounded smooth domain, M : R + → R is a function w hose behavior will be stated later, f : R + × R → R is a given nonlinear function, and ·is the usual norm in H 1 0 (Ω)givenby u 2 =  |∇ u| 2 (1.1) and finally, through this work,  u denotes the integral  Ω u(x)dx. The main goal of this paper is to establish conditions on M and f under which prob- lem (P) λ possesses a positive solution. Problem (P) λ is called nonlocal because of the presence of the term M(u 2 ) which implies that the equation i n (P) λ is no longer a pointwise identity. This provokes some mathematical difficulties which make the study of such a problem particulary interesting. Hindawi Publishing Corporation Boundary Value Problems Volume 2006, Article ID 79679, Pages 1–10 DOI 10.1155/BVP/2006/79679 2 A Kirchhoff-type equation Besides, these kinds of problems have motivations in physics. Indeed, the operator M( u 2 )Δu appears in the Kirchhoff equation, by virtue of this ( P) λ ,iscalledofthe Kirchhoff type, which arises in nonlinear vibrations, namely, u tt − M   u 2  Δu = f (x,u)inΩ × (0,T), u = 0on∂Ω × (0,T), u(x,0) = u 0 (x), u t (x,0) = u 1 (x) . (1.2) Hence, problem (P) λ is the stationary counterpart of the above evolution equation. Such a hyperbolic equation is a general version of the Kirchhoff equation ρ ∂ 2 u ∂t 2 −  P 0 h + E 2L  L 0     ∂u ∂x     2 dx  ∂ 2 u ∂x 2 = 0 (1.3) presented by Kirchhoff [14]. This equation extends the classical d’Alembert’s wave equa- tion by considering the effects of the changes in the length of the strings during the vibra- tions. The parameters in (1.3) have the following meanings: L is the length of the string, h is the area of cross-section, E is the Young modulus of the material, ρ is the mass density and P 0 is the initial tension. Problem ( 1.2) began to call the attention of several researchers mainly after the work of Lions [15], where a functional analysis approach was proposed to attack it. The reader may consult [1, 2, 8, 16, 18] and the references therein, for more informa- tion on (P) λ . Actually, problem (P) λ is a particular example of a wide class of the so-called nonlocal equations whose study has deserved the attention of many researchers, mainly in recent years. Let us cite some nonlocal problems in order to emphasize the importance of their vi TABLE OF CONTENTS ACKNOWLEDGMENTS i ABSTRACT ii TÓM TẮT iv TÓM TẮT iv TABLE OF CONTENTS vi LIST OF FIGURES ix LIST OF TABLE x INTRODUCTION 1 1.
