The curriculum vitae of Alice Turner Schafer lists two specializations: abstract algebra (group theory) and women in mathematics. As early as her high school years Alice exhibited a love for mathematics and an interest in teaching as a career. As a mathematics educator she championed the full participation of women in mathematics.

This lively, problemoriented text is designed to coach readers toward mastery of the most fundamental mathematical inequalities. With the Cauchy–Schwarz inequality as the initial guide, the reader is led through a sequence of fascinating problems whose solutions are presented as they might have been discovered — either by one of history’s famous mathematicians or by the reader.

The Eisenstein irreducibility critierion is part of the training of every mathematician. I first learned the criterion as an undergraduate and, like many before me, was struck by its power and simplicity. This article will describe the unexpectedly rich history of the discovery of the Eisenstein criterion and in particular the role played by Theodor Sch¨onemann.

The last decade has seen significant reform in the South African mathematics curriculum and the mathematics education research community has also grown markedly. Drawing on the proceedings from nearly a decade of the South African Association for Research in Mathematics, Science and Technology Education (SAARMSTE) conferences, this book reflects on the theoretical and ideological work that has contributed to the growth of mathematics education research in South Africa.

In a classic paper, Gerstenhaber showed that ﬁrst order deformations of an associative kalgebra a are controlled by the second Hochschild cohomology group of a. More generally, any nparameter ﬁrst order deformation of a gives, due to commutativity of the cupproduct on Hochschild cohomology, a graded algebra morphism Sym• (kn ) → Ext2•bimod (a, a).

The National Research Council was organized by the National Academy of Sciences in 1916 to associate the broad community of science and technology with the Academy’s purposes of furthering knowledge and advising the federal government. Functioning in accordance with general policies determined by the Academy, the Council has become the principal operating agency of both the National Academy of Sciences and the National Academy of Engineering in providing services to the government, the public, and the scientific and engineering communities.

In this concept, you will learn to find the optimal value of a function that is associated with an optimization problem. At this point, you know how to analyze a function to find its minima and maxima using the first and second derivatives. This is a big deal! Finding the solution to some realworld problem (such as in finance, science, and engineering) often involves a process of finding the maximum or minimum of a function within an acceptable region of values.

We study enhancement of diﬀusive mixing on a compact Riemannian manifold by a fast incompressible ﬂow. Our main result is a sharp description of the class of ﬂows that make the deviation of the solution from its average arbitrarily small in an arbitrarily short time, provided that the ﬂow amplitude is large enough. The necessary and suﬃcient condition on such ﬂows is expressed naturally in terms of the spectral properties of the dynamical system associated with the ﬂow. In particular, we ﬁnd that weakly mixing ﬂows always enhance dissipation in this sense. ...

The third part of the book is dedicated to analysis of role of DNA methylation in cancer. According to the American Cancer Association, nearly 13% of all deaths worldwide are cancer related. Aberrant DNA methylation patterns is likely to play a causative role in cancer initiation and development. The first chapter is dedicated to investigation of DNA methylation role in the development of hepatocellular carcinoma associated with tyrosinemia.

We study “ﬂat knot types” of geodesics on compact surfaces M 2 . For every ﬂat knot type and any Riemannian metric g we introduce a Conley index associated with the curve shortening ﬂow on the space of immersed curves on M 2 . We conclude existence of closed geodesics with prescribed ﬂat knot types, provided the associated Conley index is nontrivial. 1. Introduction If M is a surface with a Riemannian metric g then closed geodesics on (M, g) are critical points of the length functional L(γ) = γ (x)dx deﬁned on the space of unparametrized C...

Weyl group multiple Dirichlet series were associated with a root system Φ and a number ﬁeld F containing the nth roots of unity by Brubaker, Bump, Chinta, Friedberg and Hoﬀstein [3] and Brubaker, Bump and Friedberg [4] provided n is suﬃciently large; their coeﬃcients involve nth order Gauss sums. The case where n is small is harder, and is addressed in this paper when Φ = Ar . “Twisted” Dirichet series are considered, which contain the series of [4] as a special case.

We study the large eigenvalue limit for the eigenfunctions of the Laplacian, on a compact manifold of negative curvature – in fact, we only assume that the geodesic ﬂow has the Anosov property. In the semiclassical limit, we prove that the Wigner measures associated to eigenfunctions have positive metric entropy. In particular, they cannot concentrate entirely on closed geodesics. 1.

We construct many examples of nonslice knots in 3space that cannot be distinguished from slice knots by previously known invariants. Using Whitney towers in place of embedded disks, we deﬁne a geometric ﬁltration of the 3dimensional topological knot concordance group. The bottom part of the ﬁltration exhibits all classical concordance invariants, including the CassonGordon invariants. As a ﬁrst step, we construct an inﬁnite sequence of new obstructions that vanish on slice knots. These take values in the Ltheory of skew ﬁelds associated to certain universal groups. ...

The interplay between geometry and topology on complex algebraic varieties is a classical theme that goes back to Lefschetz [L] and Zariski [Z] and is always present on the scene; see for instance the work by Libgober [Li]. In this paper we study complements of hypersurfaces, with special attention to the case of hyperplane arrangements as discussed in OrlikTerao’s book [OT1]. Theorem 1 expresses the degree of the gradient map associated to any homogeneous polynomial h as the number of ncells that have to be added to a generic hyperplane section D(h) ∩ H to obtain the complement in...
