The tautological ring of ${\mathcal{M}}_{g,n}$ via Pandharipande-Pixton-Zvonkine $r$-spin relations

Reinier Kramer, Farrokh Labib, Danilo Lewanski +1

We use relations in the tautological ring of the moduli spaces ${\overline{\mathcal{M}}}_{g,n}$ derived by Pandharipande, Pixton, and Zvonkine from the Givental formula for the $r$-s…
