(1) Yes, the function that I have in mind is one-dimensional: f(t) is a
mapping from the R to C.
(2) I'm not familiar with anything Sobolev... I did some web search but couldn't understand many of the theorem statements. I will try to look at some textbooks. I did manage to find this related statement:
If |w|^s |F(w)| is in L2 and s > n + 1/2 then f(t) is n times continuously
differentiable.
How do I prove this statement? In terms of my original question, s= |

发帖数: 1037 | 30 我前面的忽略了太多的细节。你可以这样证明。
现在已经知道f是F的FT。把f写成积分的形式。
然后求(f(x+h)-f(x))/h当h->0时候的极限。利用控制收敛定理。
当然，如果钻牛角尖的话，你可以改动f在几个点的取值，使得f不连续，但FT不变。

(axb).(cxd) = (a.c)(b.d) - (a.d)(b.c) (1)
also known as identity of lagrange.
How to use the above formula to prove (axb)xc = (a.c)b - (b.c)a (2)?
I know how to prove (2) with kronecker's identities. But what's the
connection between (1) and (2)?
I don't get this from p.14 in 'Differential Geometry' by Kreyszig.
Also, what's the connection between d2x/dt2 and d2x/ds2? Problem 12.2

发帖数: 24 | 50 You may proof it in this way:
Assume you have the solution x(t, \theta) for your initial problem,
then integral your equation from [0,t] , you get
x(t,\theta)-\theta=\int_0^t \lambda(s)ds - \int_0^t p(x(s,\theta)) ds
then differential by \theta and evluate at t=0
you get
\frac{\partial x(t)}{\partial\theta}=1 at t=0
since integral domain of the second integral is [0,0], it is 0
that's it!
