A number of alternative methods, including initial works on a constrained finite element method, initiated by cFSM methods, are also detailed as they provide insights on potential future work in this area.
In 2003, Cǎdariu and Radu applied the fixed point method and they could present a short and simple proof (different from the "direct method", initiated by Hyers in 1941) for the generalized Hyers-Ulam stability of Jensen functional equation.
It is a stepwise method initiated by an analysis of the problem context, followed by identification of options, assessment, and analysis of the options' impacts, and finally sensitivity and value analysis (Bana e Costa et al. 2004).
They presented a short and a simple proof (different from the 'direct method,' initiated by Hyers in 1941) for the Cauchy functional equation [10] and for the quadratic functional equation [9].
They could present a short and simple proof (different from the direct method initiated by Hyers in 1941) for the generalized Hyers-Ulam stability of the Jensen functional and the quadratic functional equations.
They could present a short and a simple proof (different of the "direct method ", initiated by Hyers in 1941) for the Hyers-Ulam stability of Jensen functional equation [13] and for quadratic functional equation [14].
They have shown that in the particular case γ(t)= 3t, this is a continuous version of the fast gradient method initiated by Nesterov, with Φ(x t))−minHΦ="O 1t2) as t→+∞ in the worst case.
We study the existence and the continuity properties of the boundary values on the real axis of the resolvent of a self-adjoint operator H in the framework of the conjugate operator method initiated by Mourre.
The Lie symmetry method was initiated by Lie [1] in the second half of the nineteenth century.
Cardiac differentiation by hanging drop method was initiated by pipetting 20 µl drops containing ES cells onto the lid of a 10 cm petri dish, which was then inverted and placed back on the dish containing PBS.
