Maximal domains of solutions for analytic quasilinear differential equations of first order

Chong-Kyu Han, Taejung Kim

We study the real-analytic continuation of local real-analytic solutions to the Cauchy problems of quasi-linear partial differential equations of first order for a scalar function.…

The collision avoidance and the controllability for $n$ bodies in dimension one

Chong-Kyu Han, Donghoon Park

We present a method of design of control systems for $n$ bodies in the real line $R^{1}$ and on the unit circle $S^{1}$ , to be collision-free and controllable. The problem reduce…

Nullity of the Levi-form and the associated subvarieties for pseudo-convex CR structures of hypersurface type

Kuerak Chung, Chong-Kyu Han

Let $M^{2 n + 1}$ , $n \geq 1$ , be a smooth manifold with a pseudo-convex integrable CR structure of hypersurface type. We consider a sequence of CR invariant subsets $ M=\mathcal S_0 \s…

Invariant submanifolds for affine control systems

Chong-Kyu Han, Hyeseon Kim

Given an affine control system $x ˙ = f (x) + \sum_{j = 1}^{m} g_{j} (x) u_{j}$ we present an algorithmic process of construction of submanifolds that are inv…
