We prove that NIP valued fields of positive characteristic are henselian, and we begin to generalize the known results on dp-minimal fields to dp-finite fields. On any unstable dp-finite field K, we define a type-definable group of “infinitesimals,” corresponding to a canonical group topology on (K,+). We reduce the classification of positive characteristic dp-finite fields to the construction of non-trivial Aut (K/A)-invariant valuation rings.
