Dierential geometry play a fundamental role in discussing partial dierential equations(PDEs) in mathematical physics. Recently discrete dierential geometr
In this paper, we consider the three-point boundary value problem (φp(uˊˊ(t)))ˊ +a(t)f(t, u(t), uˊ(t), uˊˊ(t)) = 0, t ∈ [0, 1] subject to the boundary c
Dear Editor,Transposable phages,which are reproduced by transposition (Harshey,2012;Taylor,1963),have been widely applied in the field of biotechnology to manip
Parametric instability of a riser is caused by fluctuation of its tension in time due to the heave motion of floating plat-form. Many studies have tackled the p
