On the Spectrum of the Local $${\mathbb {P}}^2$$ Mirror Curve [PDF]
Annales Henri Poincaré, 2020 AbstractWe address the spectral problem of the formally normal quantum mechanical operator associated with the quantised mirror curve of the toric (almost) del Pezzo Calabi–Yau threefold called local $${\mathbb {P}}^2$$ P 2 in the case of complex values of Planck’s constant.

Spectrum of power laws for curved hand movements [PDF]
Proceedings of the National Academy of Sciences, 2015 Significance In curved hand movements around ellipses, the speed tends to scale inversely with the curvature with a power law having an exponent of −1/3. We examined whether this well-known regularity in motor planning holds for more general shapes. Using an optimality principle, we identified a set of basis shapes, each with a single

Geometric and Functional Analysis, 1991 Let \(\pi:\Gamma(2)\to H_ 1(\Gamma(2))\cong\mathbb{Z}^ 2\) be the canonical map and let \(R_ N:\mathbb{Z}^ 2\to(\mathbb{Z}/N\mathbb{Z})^ 2\) denote the reduction \(\bmod N\) where \(N\geq 1\) is an integer. The group \(\Phi(N):=\text{ker}(R_ N\circ\pi)\) defines an abelian Galois covering \(\Phi(N)\backslash\mathbb{H}\) of \(\Gamma(2)\backslash\mathbb ...

Spectrum curves for a discrete Sturm–Liouville problem with one integral boundary condition
Nonlinear Analysis, 2019 This paper presents new results on the spectrum on complex plane for discrete Sturm–Liouville problem with one integral type nonlocal boundary condition depending on three parameters: γ, ξ1 and ξ2.

On the Spectrum of Curved Planar Waveguides
Publications of the Research Institute for Mathematical Sciences, 2005 The spectrum of the Laplace operator in a curved strip of constant width built along an infinite plane curve, subject to three different types of boundary conditions (Dirichlet, Neumann and a combination of these ones, respectively), is investigated. We prove that the essential spectrum as a set is stable under any curvature of the reference curve which ...

Spectrum Curves for Sturm–Liouville Problem with Integral Boundary Condition
Mathematical Modelling and Analysis, 2015 We consider Sturm–Liouville problem with one integral type nonlocal boundary condition depending on three parameters γ (multiplier in nonlocal condition), ξ1, ξ2 ([ξ1, ξ2] is a domain of integration).

Motions of Curves in the Projective Plane Inducing the Kaup-Kupershmidt Hierarchy [PDF]
, 2012 The equation of a motion of curves in the projective plane is deduced. Local flows are defined in terms of polynomial differential functions. A family of local flows inducing the Kaup-Kupershmidt hierarchy is constructed.
