Structure theorems for braided Hopf algebras

Journal of Topology, Volume 18, Issue 4, December 2025.
Abstract We develop versions of the Poincaré–Birkhoff–Witt and Cartier–Milnor–Moore theorems in the setting of braided Hopf algebras. To do so, we introduce new analogs of a Lie algebra in the setting of a braided monoidal category, using the notion of a braided operad.

Existence and orthogonality of stable envelopes for bow varieties

Bulletin of the London Mathematical Society, Volume 57, Issue 11, Page 3249-3306, November 2025.
Abstract Stable envelopes, introduced by Maulik and Okounkov, provide a family of bases for the equivariant cohomology of symplectic resolutions. They are part of a fascinating interplay between geometry, combinatorics and integrable systems. In this expository article, we give a self‐contained introduction to cohomological stable envelopes of type A$A$

Holomorphic field theories and higher algebra

Bulletin of the London Mathematical Society, Volume 57, Issue 10, Page 2903-2974, October 2025.
Abstract Aimed at complex geometers and representation theorists, this survey explores higher dimensional analogs of the rich interplay between Riemann surfaces, Virasoro and Kac‐Moody Lie algebras, and conformal blocks. We introduce a panoply of examples from physics — field theories that are holomorphic in nature, such as holomorphic Chern‐Simons ...

Two edge contractions for the affine super Yangian [PDF]

In the previous paper, we constructed two kinds of edge contractions for the affine super Yangian. In this article, we show that these two edge contractions are commutative with each other.

Quantized universal enveloping superalgebra of type Q and a super-extension of the Hecke algebra

Letters in Mathematical Physics, 1992
The ``strange'' Lie superalgebra \(q(n)\) is unfriendly in several ways: The Cartan subalgebra is not purely even, there is no invariant bilinear form and no quadratic Casimir operator. In some other respects the algebra has properties analogous to those of the general linear algebra \(\text{gl}(n)\).
