title: Analysis of backward differentiation formula for nonlinear differential-algebraic equations with 2 delays.
abstract: This paper is concerned with the backward differential formula or BDF methods for a class of nonlinear 2-delay differential algebraic equations. We obtain two sufficient conditions under which the methods are stable and asymptotically stable. At last, examples show that our methods are true.
