Biography

Duncan Clark holds a Ph.D. in Mathematics from Ohio State University. His main research interests are algebraic topology and homotopy theory. More specifically, Clark is interested in Goodwillie's calculus of homotopy functors: including structure inherent to the derivatives of functors, and applications of the theory to categories of structured ring spectra.

On the Goodwillie derivatives of the identity in structured ring spectra

arXiv:2004.02812

The aim of this paper is three-fold: (i) we construct a naturally occurring highly homotopy coherent operad structure on the derivatives of the identity functor on structured ring spectra which can be described as algebras over an operad  in spectra, (ii) we prove that every connected -algebra has a naturally occurring left action of the derivatives of the identity, and (iii) we show that there is a naturally occurring weak equivalence of highly homotopy coherent operads between the derivatives of the identity on -algebras and the operad .

The partition poset complex and the Goodwillie derivatives of the identity in spaces

arXiv:2007.05440

We produce a canonical highly homotopy-coherent operad structure on the derivatives of the identity functor in spaces via a pairing of cosimplicial objects, providing a new description of an operad structure on such objects first described by Ching. In addition, we show the derived primitives of a commutative coalgebra in spectra form an algebra over this operad.
