From the point of view of conformal theory, this story is about modular transformations in the WZNW model [18]. We briefly remind this story in subsection (). However, from the point of view of modular transformations, the even simpler case would be those of Liouville and WN -models. Thus, we begin from them in the next subsection In each case, a finite system of fundamental invariants is determined and the class group of the invariant algebra is calculated. In some cases, a presentation and a Hironaka decomposition of the.

This chapter presents an analysis of the cusps on Hilbert modular varieties and values of presents an explicit formula for φ(M,V) in terms of the triangulation of R n −1 /V generalizing Hirzebruch's formula in the case n = 2. The chapter discusses a new idea for calculating L(M, V, 1) that would lead to the same closed formula for L(M, V,1) as for φ(M, V).

A FUNDAMENTAL SYSTEM OF INVARIANTS OF A MODULAR GROUP OF TRANSFORMATIONS* BY JOHN SIDNEY TURNER 1. Introduction. Let G be any given group of g homogeneous linear trans-formations on the indeterminates xi, • • •, x„, with integral coefficients taken modulo m.

Hurwitzf raised the question of the existence of a finite funda. A Fundamental System of Invariants of the General Modular Linear Group with a Solution of the Form Problem is an article from Transactions of the American. In mathematics, a modular invariant of a group is an invariant of a finite group acting on a vector space of positive characteristic (usually dividing the order of the group).

The study of modular invariants was originated in about by Dickson (). Dickson invariant. When G is the finite general linear group GL n (F q) over the finite field F q of order a prime power q acting on the.

We shall determine m functions which form a fundamental system of invariants for the group Gm of all linear homogeneous transformations on m. ] L. DICKSON: MODULAR INVARIANTS Absolute and relative invariants of a system of forms.

When L is the group G of all m-ary linear homogeneous transformations in the GF\\p*~\, the invariants defined in §§3, 4 are called the absolute invariants of the s forms. When L is the group Gx of all transformations of. Invariant theory is a branch of abstract algebra dealing with actions of groups on algebraic varieties, such as vector spaces, from the point of view of their effect on cally, the theory dealt with the question of explicit description of polynomial functions that do not change, or are invariant, under the transformations from a given linear group.

modular and the algebraic invariant principles by emphasizing the process of transvection between a given form and the universal covariants of the modular group of binary transformations G(P2_P)(P«_d. The chief difficulty encountered was the apparent one that this process is.

The notions of a group, an invariant and the fundamental problems of the theory were formulated at that time in a precise manner and gradually it became clear that various facts of classical and projective geometry are merely expressions of identities (syzygies) between invariants or covariants of the corresponding transformation groups.

Fundamental system of modular invariants INVARIANTS OF A MODULAR GROUP. FORMAL INVARIANTS AND COVARIANTS OF MODULAR FORMS. A simple theory of invariants for the modular forms and linear transformations employed in the theory of numbers should be of an importance commensurate with that of the theory of.

Knot invariants in this case can be constructed as traces of the corresponding braid group elements: (2) Inv (b) = Tr R β (b), b ∈ B n, R: b → β Here b is an element of Artin's braid group of n elements B n and the trace is taken in some representation R. For this to give an invariant the trace operation must respect the two Markov moves.

simplicity of the relations between the invariants, common to the algebraic and modular theories, and the additional invariants peculiar to the modular theory. In the study of the invariants of a given quantic in the Galois field of order pn, we have a doubly infinite system of problems, corresponding to a single.

A fundamental invariant is an element of a set of generators for a ring of invariants. A fundamental system is a set of generators (for a ring of invariants, covariants, and so on). G Gordan Named for Paul Gordan.

Gordan's theorem states that the ring of invariants of a binary form (or several binary forms) is finitely generated. A Fundamental System of Invariants of the General Modular Linear Group with a Solution of the Form Problem on a polynomial ring by linear transformations of the indeterminates.

Mildred Sanderson (–) was an American mathematician, best known for her mathematical theorem concerning modular invariants. Life. Sanderson was born in Waltham, Massachusetts, in and was the valedictorian of her class at the Waltham High School.

She graduated from Mount Holyoke College inwinning Senior Honors in Mathematics. She obtained her Ph.D degree from the. In mathematics, the modular group is the projective special linear group PSL(2, Z) of 2 × 2 matrices with integer coefficients and unit matrices A and −A are identified.

The modular group acts on the upper-half of the complex plane by fractional linear transformations, and the name "modular group" comes from the relation to moduli spaces and not from modular arithmetic.

A Fundamental System of Invariants of the General Modular Linear Group with a Solution of the Form Problem A Fundamental system of invariants of a modular group of transformations. The Abelan integrals and differentials, and thereby the modular forms, as a generalization of the modular functions, lead to the modular functions on Γ 1.

We also owe to Klein the congruence group. These are subgroups Γ 1 of Γ that contain the group of all transformations;a ≡ d ≡ ± 1, b ≡ c ≡ 0 mod m. for fixed natural number m.Equation () is the modular transformation property for Riemann theta functions.

The modular transformations form a group under the composition of such transformations, the modular group, which is generated by simpler transformations, for which ξ (Γ) is determinate.transformation, like the transformation of the points in a plane by a linear transformation of their co ordinates.

Invariant theory treats of the properties of the system which persist, or its elements which remain unaltered, during the changes which are imposed upon the system by the transformation.
