Betti maps, Pell equations in polynomials and almost-Belyi maps [PDF]

open access: yes, 2022
We study the Betti map of a particular (but relevant) section of the family of Jacobians of hyperelliptic curves using the polynomial Pell equation A(2) - DB2 = 1, with A, B, D is an element of C[t] and certain ramified covers P-1 -> P-1 arising from ...

Dirichlet and Neumann Problems for String Equation, Poncelet Problem and Pell-Abel Equation [PDF]

open access: yes, 2006
We consider conditions for uniqueness of the solution of the Dirichlet or the Neumann problem for 2-dimensional wave equation inside of bi-quadratic algebraic curve.

On the double EPW sextic associated to a Gushel-Mukai fourfold [PDF]

open access: yes, 2018
In analogy to the case of cubic fourfolds, we discuss the conditions under which the double cover $\tilde{Y}_A$ of the EPW sextic hypersurface associated to a Gushel-Mukai fourfold is birationally equivalent to a moduli space of (twisted) stable sheaves ...

The Zeldovich approximation: key to understanding Cosmic Web complexity [PDF]

open access: yes, 2013
We describe how the dynamics of cosmic structure formation defines the intricate geometric structure of the spine of the cosmic web. The Zeldovich approximation is used to model the backbone of the cosmic web in terms of its singularity structure.

Torsion points, Pell's equation, and integration in elementary terms [PDF]

open access: yes, 2020
The main results of this paper involve general algebraic differentials $\omega$ on a general pencil of algebraic curves. We show how to determine if $\omega$ is integrable in elementary terms for infinitely many members of the pencil.

Bias, the Brain, and Student Evaluations of Teaching [PDF]

open access: yes, 2007
Student evaluations of teaching are a common fixture at American law schools, but they harbor surprising biases. Extensive psychology research demonstrates that these assessments respond overwhelmingly to a professor’s appearance and nonverbal behavior;

Hyperelliptic continued fractions and generalized jacobians [PDF]

open access: yes, 2019
For a complex polynomial D(t) of even degree, one may define the continued fraction of D(t). This was found relevant already by Abel in 1826, and then by Chebyshev, concerning integration of (hyperelliptic) differentials; they realized that, contrary to ...

Designing Scholarships To Improve College Success: Final Report On the Performance-Based Scholarship Demonstration [PDF]

open access: yes, 2015
Performance-based scholarships have two main goals: to give students more money for college and to provide incentives for academic progress. They are designed to reduce the financial burden on low-income students and help them progress academically by ...
