Arc spaces have been introduced in algebraic geometry as a tool to study singularities but they show strong connections with combinatorics as well. Exploiting these relations, we obtain a new approach to the classical Rogers–Ramanujan Identities. The linking object is the Hilbert–Poincaré series of the arc space over a point of the base variety. In the case of the double point, this is precisely the generating series for the integer partitions without equal or consecutive parts. 
Quadratic ideals and Rogers–Ramanujan recursions
We give an explicit recursive description of the Hilbert series and Gröbner bases for the family of quadratic ideals defining the jet schemes of a double point. We relate these recursions to theExpand
A framework of Rogers–Ramanujan identities and their arithmetic properties
The two Rogers-Ramanujan q-series where σ 0; 1, play many roles in mathematics and physics. By the Rogers- Ramanujan identities, they are essentially modular functions. Their quotient, theExpand

Partition Identities and Application to Infinite-Dimensional Gröbner Basis and Vice Versa
In the first part of this article, we consider a Groebner basis of the differential ideal {x_1^2} with respect to "the" weighted lexicographical monomial order and show that its computation isExpand
Jet schemes of rational double point singularities
We prove that for m ∈ N, m big enough, the number of irreducible components of the schemes of m−jets centered at a point which is a double point singularity is independent of m and is equal to theExpand

We conjecture that the stable Khovanov homology of torus knots can be described as the Koszul homology of an explicit irregular sequence of quadratic polynomials. The corresponding Poincaré seriesExpand
