solution of non-autonomous inhomogeneous boundary Cauchy problems, this solution is given by a variation of constants formula.. Then, we apply this result to show the existence
The focus of our present work is to establish the existence of almost periodic solutions of neutral functional differential equations by using the Razumikhin-type argument.. The
Based on the Schauder type estimates, under some assumptions on the mobility and terms of lower order, we establish the global existence of classical
theorem, energy method introduced by Lions [6] and technical ideas to show existence, regularity and uniqueness of strong solutions for the problem (1.1)-(1.9).. We show that
Abstract By means of the fixed point index theory of strict set contraction operators, we establish new existence theorems on multiple positive solutions to a boundary value problem
That is, some authors have used fixed point theorems to show the existence of pos- itive solutions to boundary value problems for ordinary differential equations, difference
Given a surface or scattered data points from a surface in 3-space, we show how to approximate the given data by a ruled surface in tensor product B-spline representation1. This
Given an a priori valuation rule u , we define the associated a posteriori valuation rule h by an indifference argument: The u -value of optimally investing in the financial
