m> 2 for x / 2 Would not recognize the problem, help is
I'm sorry my English is poor.
u[x_, 0] := 0
du[x_, m_] := D[u[x, m], x]
\[Chi][m_] := Piecewise[{{0, m < 2}, {1, m \[GreaterSlantEqual] 2}}]
u[x_, m_] := \[Chi][m] u[x, m - 1] + h*\!\(
\*SubsuperscriptBox[\(\[Integral]\), \(0\), \(a\)]\(\((du[x, m - 1] -
1 + 2\ \((
\*UnderoverscriptBox[\(\[Sum]\), \(j = 0\), \(m - 1\)]\((u[
\*FractionBox[\(x\), \(2\)], j]\ u[
\*FractionBox[\(x\), \(2\)],
m - 1 - j])\))\))\) \[DifferentialD]x\)\) /. a :> x
