Floyd's manifold is a conjugation space
E. E. Floyd showed in 1973 that there exist only two nontrivial cobor-dism classes that contain manifolds with three cells, and that they lie in dimen-sions 10 and 5. We prove that there is an action of the cyclic group C2 on the 10-dimensional Floyd manif ...
Pisa2023Piecewise Affine Curvature model: a reduced-order model for soft robot-environment interaction beyond PCC
Josephine Anna Eleanor Hughes, Francesco Stella, Qinghua Guan
Soft robot are celebrated for their propensity to enable compliant and complex robot-environment interactions. Soft robotic manipulators, or slender continuum structure robots have the potential to exploit these interactions to enable new exploration and m ...
IEEE2023Fast parametric analysis of trimmed multi-patch isogeometric Kirchhoff-Love shells using a local reduced basis method
Annalisa Buffa, Pablo Antolin Sanchez, Margarita Chasapi
This contribution presents a model order reduction framework for real-time efficient solution of trimmed, multi-patch isogeometric Kirchhoff-Love shells. In several scenarios, such as design and shape optimization, multiple simulations need to be performed ...
2023Fast and accurate decoding of finger movements from ECoG through Riemannian features and modern machine learning techniques
Objective. Accurate decoding of individual finger movements is crucial for advanced prosthetic control. In this work, we introduce the use of Riemannian-space features and temporal dynamics of electrocorticography (ECoG) signal combined with modern machine ...
IOP Publishing Ltd2022Coarse graining and large-N behavior of the d-dimensional N-clock model
We study the asymptotic behavior of the N-clock model, a nearest neighbors ferromagnetic spin model on the d-dimensional cubic epsilon-lattice in which the spin field is constrained to take values in a discretization S-N of the unit circle S-1 consisting o ...
2021Dubrovin'S Superpotential As A Global Spectral Curve
We apply the spectral curve topological recursion to Dubrovin's universal Landau-Ginzburg superpotential associated to a semi-simple point of any conformal Frobenius manifold. We show that under some conditions the expansion of the correlation differential ...
CAMBRIDGE UNIV PRESS2019Some regularity results for p-harmonic mappings between Riemannian manifolds
Let M be a C-2-smooth Riemannian manifold with boundary and N a complete C-2-smooth Riemannian manifold. We show that each stationary p-harmonic mapping u: M -> N, whose image lies in a compact subset of N, is locally C-1,C-alpha for some alpha is an eleme ...
2019Arithmetic and metric aspects of open de Rham spaces
Dimitri Stelio Wyss, Tamás Hausel, Michael Lennox Wong
In this paper we determine the motivic class---in particular, the weight polynomial and conjecturally the Poincar'e polynomial---of the open de Rham space, defined and studied by Boalch, of certain moduli of irregular meromorphic connections on the trivia ...
2018Motivic and p-adic Localization Phenomena
In this thesis we compute motivic classes of hypertoric varieties, Nakajima quiver varieties and open de Rham spaces in a certain localization of the Grothendieck ring of varieties. Furthermore we study the -adic pushforward of the Haar measure under a ...
EPFL2017Dynamical Low Rank approximation of PDEs with random parameters
In this work, we focus on the Dynamical Low Rank (DLR) approximation of PDEs equations with random parameters. This can be interpreted as a reduced basis method, where the approximate solution is expanded in separable form over a set of few deterministic b ...
