Sunto

Si studiano limiti di punti di Weierstrass per degenerazioni di curve lisce a curve stabili di tipo non compatto, unione di due componenti lisce irriducibili che si intersecano trasversalmente in $m \ge 1$ punti. Il caso $m = 1$, essendo di tipo compatto, è già stato trattato da Eisenbud e Harris in [8], sicché nella presente Nota verrà analizzata la situazione per $m > 1$.
