Does the motor cortex draw on a wire plane?
Patrick Iglesias-Zemmour
The two-thirds power law of human motor control () is geometrically equivalent to constant equi-affine speed. In classical differential geometry, however, the e…
Bosonic and Fermionic Singularities in Diffeology
Patrick Iglesias-Zemmour
We explore the differential geometry of the quadrant , equipped with the subset diffeology of . We show a striking dichotomy between differential…
Geometric Quantization by Paths, Part III: The Metaplectic Anomaly
Patrick Iglesias-Zemmour
In the previous parts of this work, we established the Prequantum Groupoid as the universal geometric container for quantum mechanics. This approach, which we call t…
Geometric Quantization by Paths Part II: The General Case
Patrick Iglesias-Zemmour
In Part I, we established the construction of the Prequantum Groupoid for simply connected spaces. This second part extends the theory to arbitrary connected parasymplectic diffeol…
A Conformal Co-Symplectic Structure on the Space of Pseudo-Riemannian Geodesics
Patrick Iglesias-Zemmour
The classical construction of the symplectic structure on the space of geodesic trajectories via Hamiltonian reduction fails in the pseudo-Riemannian setting due to a dimensional m…
Groupoids in Diffeology
Patrick Iglesias-Zemmour
This expository paper recounts the development and application of the concept of the diffeological groupoid, from its introduction in 1985 to its use in current research. We demons…
