### There are many interactions between noncommutative algebra

theory on the one hand and classical algebraic geometry on the other, with important applications in both directions. The aim of this book is to provide a comprehensive introduction to some of the most signiﬁcant topics in this area, including noncom-mutative projective algebraic geometry, deformation theory, symplectic reﬂection

### Computing Zeta Functions of Nondegenerate Curves

An important research topic in computational number theory is the determination of the number of rational points on an algebraic curve C over a ﬁnite ﬁeld Fpn. More generally, one is interested in the computation of its Hasse-Weil zeta function ZC(t) = exp X∞ k=1 #C(Fpnk) tk k! ∈Q[[t]],

the family in characteristic pvia -adic Fourier transforms. The moment zeta functions of the Dwork family are computed in [11]. In [10], the zeta functions for more general monomial deformations of Fermat type hypersurfaces in weighted projective spaces are studied via Dwork s deformation theory.

A simple computation shows that L(E f=K;s) = X n 1 a nr(n)n s; where r(n) is the number of integral ideals in Kof norm n. In other words, nth coe cient in the above Dirichlet series is the product of the nth coe cient in L(E f=Q;s) and the nth coe cient of the Dedekind zeta function of K. The way to understand this type of product

In studying the Zeta function using ℓ-adic cohomology, Katz proved that there was a link between more general monomial deformations of Fermat hypersurfaces (of which the Dwork family is an example) and hypergeometric sheaves [20].

j is a zero of the Selberg zeta function, and the question of how certain L-functions behave at these points appears in the work of Phillips and Sarnak [23] on deformation of cusp forms. These points are also distinguished in the ana-lytic theory of L-functions for leading to conductor dropping. The latter phenomenon

The transform is unitary and it may be built from unitary gates, namely the Hadamard gate H = p1 2 ( x + z) and the series Bk = 0 @ 1 0 0 e 2 i 2k 1 A By analogy, a mass computation with 3N basis states uses ternary digits, so the gates Bk would be replaced by gates
