Cusp Forms of Weight 2 for the Group Γ 2 (4, 8)

Riccardo Salvati-Manni, Jaap Top
1993 American Journal of Mathematics  
This Hg plays the same role in the theory of abelian varieties over the complex numbers, as the usual upper half plane does in the theory of elliptic curves.  ...  Using this lifting procedure he is able to prove his conjecture for simple abelian surfaces which are (upto isogeny) factors of the jacobian of a modular curve Xo(p) where p is a prime number not congruent  ...  For any pair of odd theta characteristics m = (ml,m2,M3,M4) and n = (nl, n2, n3, 2trace(tMx) det(X +M) exp ri(trace((X +M')T(X +M')).  ...

Quantum variance on quaternion algebras, I [article]

Paul D. Nelson
2016 arXiv   pre-print
Our results compare to those obtained by Luo--Sarnak, Zhao, and Sarnak--Zhao on the modular curve, whose method required a cusp.  ...  Our method uses the theta correspondence to reduce the problem to the estimation of metaplectic Rankin--Selberg convolutions. We apply it here to the first non-split case.  ...  We are grateful to many people for their contributions to this project. P. Sarnak introduced us to his work with W.  ...

Manifestations of classical phase space structures in quantum mechanics

O. Bohigas, S. Tomsovic, D. Ullmo
1993 Physics reports  
Using two coupled quanic oscillators for illustration, the quantum mechanics of simple systems whose classical analogs have varying degrees of non-integrability is investigated.  ...  This allows us to probe deeply into the workings of semiclassical quantizatlon in mixed phase space systems. Some observations of intermediate status states are made.  ...  One of us (S.T.) was supported by the Joliot-Curie Foundation, the Centre National de la Recherche Scientifique and the National Science Foundation (Grant number CHE-90l4555).  ...

Factoring integers with the number field sieve [chapter]

J. P. Buhler, H. W. Lenstra, Carl Pomerance
1993 Lecture notes in mathematics  
The present paper is devoted to the description and analysis of a more general version of the number field sieve.  ...  This is asymptotically faster than all other known factoring algorithms, such äs the quadratic sieve and the elliptic curve method.  ...  For mi one tries several values with m^ κ, nl^d+l\ until one discovers a value for which n -mf is found to have a divisor m^ with mi « n1/^"1"1^; for example, by trial division or by the elliptic curve  ...

On the Precession of a Viscous Spheroid, and on the Remote History of the Earth
