Functional integration over geometries [PDF]
Journal of Mathematical Physics, 1995 The geometric construction of the functional integral over coset spaces ℳ/𝒢 is reviewed. The inner product on the cotangent space of infinitesimal deformations of ℳ defines an invariant distance and volume form, or functional integration measure on the full configuration space.

Integrability and geometry of the Wynn recurrence
Numerical Algorithms, 2022 We show that the Wynn recurrence (the missing identity of Frobenius of the Padé approximation theory) can be incorporated into the theory of integrable systems as a reduction of the discrete Schwarzian Kadomtsev-Petviashvili equation. This allows, in particular, to present the geometric meaning of the recurrence as a construction of the appropriately ...

Noncommutative Geometry and Integrable Models
Letters in Mathematical Physics, 1997 A construction of conservation laws for $σ$-models in two dimensions is generalized in the framework of noncommutative geometry of commutative algebras. This is done by replacing the ordinary calculus of differential forms with other differential calculi and introducing an analogue of the Hodge operator on the latter.

On the Geometry of No-Boundary Instantons in Loop Quantum Cosmology
Universe, 2019 We study the geometry of Euclidean instantons in loop quantum cosmology (LQC) such as those relevant for the no-boundary proposal. Confining ourselves to the simplest case of a cosmological constant in minisuperspace cosmologies, we analyze solutions of ...
