10 results for L-invariants

New invariant defined for Weinstein domains, related to Kirby-Thompson's invariant.

problem Defining a symplectic invariant for Weinstein domains.
method Contact cut graph, Lefschetz fibrations, multisections with divides.
result Definition of Weinstein L\mathcal{L}-invariant and its relation to Kirby-Thompson's invariant.

In this paper, we introduce the relative L\mathcal{L}-invariant rL(X)r\mathcal{L}(X) of a smooth, orientable, compact 4-manifold XX with boundary. This invariant is defined by measuring the lengths of certain paths in the cut complex of a trisection surface for XX. This is motivated by the definition of the $\mathcal{L…

The paper describes metrics on left Leibniz algebras, linking them to quadratic Lie algebras.

problem Understanding metrics on left Leibniz algebras and their connections to quadratic Lie algebras.
method Analyzing left multiplications, right multiplications, and bilinear forms on left Leibniz algebras.
result Left Leibniz algebras with associative metrics can be derived from their underlying quadratic Lie algebras.

In this paper we study the scalar geometries occurring in the dimensional reduction of minimal five-dimensional supergravity to three Euclidean dimensions, and find that these depend on whether one first reduces over space or over time. In both cases the scalar manifold of the reduced theory is described as an eight-di…

To a closed wide Lie subgroupoid A\mathbf{A} of a Lie groupoid L\mathbf{L}, i.e. a Lie groupoid pair, we associate an Atiyah class which we interpret as the obstruction to the existence of L\mathbf{L}-invariant fibrewise affine connections on the homogeneous space L/A\mathbf{L}/\mathbf{A}. For Lie groupoid pairs with…

Proposes a new framework for invariant quadratic P&L predictions in option books.

problem Inconsistent second-order P&L predictions across different factor parameterizations.
method Local, model-agnostic framework using covariant Hessian defined by an affine connection.
result Coordinate-invariant quadratic P&L predictions that match desk targets.
