On the quasiuniqueness of solutions of degenerate equations in Hilbert space (Q1098986)

Summary: We study the quasiuniqueness (i.e., \(f_ 1\doteq f_ 2\) if \(f_ 1-f_ 2\) is flat, the function f(t) being called flat if, for any \(K>0\), \(t^{-K} f(t)\to 0\) as \(t\to 0)\) for ordinary differential equations in Hilbert space. The case of inequalities is studied, too.
