# can the Newton's identities and Dodgson's condensations be proved by Gessel-Viennot's lemma?

Gessel-Viennot's simple but powerful lemma has many striking applications, such as counting noninsecting paths , proving the Jacob-Trudi's identities, and solving the aztec diamond problem. So I wonder wether it can also be used to prove the Dodgson's condensation and Newton's indentities. Also, if you know other theorems or identities that can be solved by this lemma, please let me konw...

I think that Viewing determinants as nonintersecting lattice paths yields classical determinantal identities bijectively by Markus Fulmek is your friend.
