Some remarks on Dupont contraction.
Published 2018-01-01“…We present an alternative equivalent description of Dupont's simplicial contraction: it is an explicit example of a simplicial contraction between the simplicial differential graded algebra of polynomial differential forms on standard simplices and the space of Whitney elementary forms.…”

Formality in generalized Kähler geometry
Published 2007“…This is done by showing that a certain differential graded algebra associated to a generalized complex manifold is formal in the generalized Kahler case, while it is never formal for a generalized complex structure on a nilpotent Lie algebra.…”

Open-string integrals with multiple unintegrated punctures at genus one
Published 2022-10-01“…The KZB equations in the so-called universal case is written in terms of the genus-one Drinfeld-Kohno algebra t $$ \mathfrak{t} $$ 1,N ⋊ d $$ \mathfrak{d} $$ , a graded algebra. Our construction determines matrix representations of various dimensions for several generators of this algebra which respect its grading up to commuting terms.…”

A new algebraic structure in the standard model of particle physics
Published 2018-06-01“…B is the fundamental object in our approach: we show that (nearly) all of the basic axioms and assumptions of the traditional real-spectral-triple formalism of NCG are elegantly recovered from the simple requirement that B should be a differential graded ∗-algebra (or “∗-DGA”). Moreover, this requirement also yields other, new, geometrical constraints. …”

Geometric invariant theory for graded unipotent groups and applications
Published 2018“…Given any action of U on a projective variety X extending to an action of U which is linear with respect to an ample line bundle on X, then provided that one is willing to replace the line bundle with a tensor power and to twist the linearisation of the action of U by a suitable (rational) character, and provided an additional condition is satisfied which is the analogue of the condition in classical GIT that there should be no strictly semistable points for the action, we show that the U-invariants form a finitely generated graded algebra; moreover the natural morphism from the semistable subset of X to the enveloping quotient is surjective and expresses the enveloping quotient as a geometric quotient of the semistable subset. …”
