Proves norm inflation for cubic hyperbolic NLS on T^2 in H^s for s ≤ 1/2 (s ≠ 0), establishing ill-posedness below the scaling-critical regularity s=1/2 in contrast to local well-posedness for s > 1/2.

Low-regularity Schr\"odinger map flow on high-dimensional periodic domains
Proves local well-posedness for Schrödinger map flow from T^d to S^2 at σ > d/2 + 1/2 (d≥3) and to general compact Kähler N at σ > d/2 + 5/6 (d≥2), first such low-regularity result in periodic setting.

Norm inflation for the cubic hyperbolic NLS on $\mathbb T^2$
Proves norm inflation for cubic hyperbolic NLS on T^2 in H^s for s ≤ 1/2 (s ≠ 0), establishing ill-posedness below the scaling-critical regularity s=1/2 in contrast to local well-posedness for s > 1/2.
