The boundary layer approximation and nonlinear waves in elastic tubes

Antar, Nalan; Demiray, Hilmi (Pergamon-Elsevier Science, 2000-09)

In the present work, employing the nonlinear equations of an incompressible, isotropic and elastic thin tube and approximate equations of an incompressible viscous fluid, the propagation of weakly nonlinear waves is examined. ...

Boundary value problem of Caputo fractional differential equations of variable order

Ahmed, Refice; Özer, Özen; Mohammed Said, Souid (Işık University Press, 2023-07)

In this work, we investigate the existence, uniqueness and the stability of solutions to the boundary value problem (BVP) of Caputo fractional differential equations of variable order by converting it into an equivalent ...

Boundary value problem solving for semilinear fractional differential equations with nonlocal and integral boundary conditions

Tellab, Brahim (Işık University Press, 2022)

In this paper, we will study a boundary value problem for semilinear fractional differential equations of order q ∈ (1, 2] with nonlocal and integral boundary conditions. Some existence and uniqueness results with illustrative ...

Bounded harmonic mappings related to starlike functions

Varol, Dürdane; Aydoğan, Seher Melike; Polatoğlu, Yaşar (Amer Inst Physics, 2014-12-17)

Let f = h(z) + <(g(z))over bar> be a sense-preserving harmonic mapping in the open unit disc D = {z vertical bar vertical bar z vertical bar < 1}. If f satisfies the condition vertical bar 1/b(1) g'(z)/h' (z) - M vertical ...
