Math 424, Advanced Calculus

It is a basic premise in 400 level math courses that understanding a topic meansthat one can construct proofs about the objects being studied. A student must knowdefinitions, be able to construct examples (with proofs that they are examples), readand understand proofs of theroems, and apply theory in situations that are new tothe student.

Real Numbers

• Students will understand the role of the Completeness Axiom in establishingfundamanetal properties of the real numbers.

• Students will know and use terminology regarding basic topology of the realline.

• Students will prove facts about real numbers using suprema, infima, and ored-ered field properties.

Limits and Continuity

• Students will know and understand the ǫ-δ definition of a limit of a function.

• Students will know and understand the ǫ-δ definition of continuity of a function.

• Students will know the definition of uniform continuity of a function and beable to compare and contrast it with the definition of pointwise continuity.

• Students will know the statements and proofs of the fundamental theoremsregarding limits and continuous functions.

• Students will know how the fundamental theroems regarding limits and con-tinuous functions are applied in a standard Calculus course.

Differentiable Functions

• Students will know and understand the limit definition of the derivative.

• Students will know the statements and proofs of the fundamental theoremsregarding differentiable functions.

• Students will know how the fundamental theroems regarding differentiablefunctions are applied in a standard Calculus course.

Math 430, Complex Variables

1. Students will learn the arithmetic of complex numbers in terms of their fieldproperties. Students will learn the geometry of complex numbers in terms ofmodulus and argument. Students’ main task at this level is to learn threerepresentations of complex numbers:

• an indivisible point z,

• rectangular form a+ bi = Re z + i Im z,

• polar form reiθ = |z|ei arg z,

and to know which type of arguments require (or lend themselves most readilyto) which form. Students will compute powers and roots of complex numbers,developing both their algebraic and geometric intuition.

2. Students will grapple with the “branch cut issue” that first arises with thedefinition of a single-valued argument and reappears with the definition of theprincipal value of the logarithm.

3. Functions of a complex variable. Students will interpret functions as map-ping the complex plane to itself. They will determine images under variousmaps both graphically and using set-builder notation. They will learn limitsand continuity in the complex plane.

4. Complex differentiation. Students will carefully explore the notion of an-alyticity. They will compute derivatives from the definition, they will showfunctions to be not differentiable or not analytic using the definition, and theywill interpret the derivative geometrically. Students will prove the necessityand (“almost”) sufficiency of the Cauchy-Riemann equations. Students willapply the Cauchy-Riemann equations to reach various conclusions, such asfunctions being constant on a domain. Specific analytic functions, whose prop-erties students will study in detail, will be polynomials and rational functions,exponential, trigonometric, and hyperbolic functions, and the logarithmic func-tion. Students will determine domains of analyticity for logarithmic and powerfunctions, including “branch picking.”

5. Complex integration. Students will parametrize contours and compute con-tour integrals. They will interpret the contour integral using parametrizedcurves and show its independence of (admissible) parametrization. Studentswill prove and apply a result on bounding contour integrals of bounded func-tions. Students will prove and apply every direction of the result that a contin-uous function in a domain has an antiderivative throughout the domain if andonly if all its loop integrals in the domain vanish if and only if its integrals arepath-independent throughout the domain. Students will construct counterex-amples if a hypothesis is not met. Students will interpret contour integrals interms of line integrals and use Green’s Theorem to prove Cauchy’s IntegralTheorem, connecting the notion of analyticity to antiderivatives. They willuse this theorem to simplify the computation of integrals. Students will proveCauchy’s Integral Formula, and its generalized version, use it to prove thatanalytic functions have analytic derivatives, and apply it in the computationof contour integrals. Finally, students will prove Liouville’s Theorem in orderto prove the Fundamental Theorem of Algebra.

6. Possible additional topics include the stereographic projection, series and residues,and conformal mapping.

Math 487, Algebraic Structures

Math 487 is a one semester course in Abstract Algebra, addressing the fundamentalsof group theory, and providing an introduction to the theory of rings and fields.Students who successfully complete this course will be expected to:

• Build a catalog of examples of groups displaying a wide variety of properties:finite versus infinite, cyclic versus more than one generator, abelian versus nonabelian, permutation groups, and their subgroups; for each group within thiscatalog, students should be able to compute, describe structures, prove groupproperties, and apply these examples in other contexts.

• Prove statements where an axiomatic definition appears as either a hypothesisor conclusion of an implication.

• Communicate mathematics clearly using the appropriate terminology, nota-tions and definitions, and use definitions to determine the structure of proofs.

• Describe the concept of isomorphism and properties of isomorphic groups, pro-vide examples of isomorphic groups, and prove that two groups are isomorphic.

• Find and describe the cosets of a subgroup within a group, prove properties ofcosets, and use properties of cosets to understand Lagrange’s Theorem; applyLagrange’s theorem to describe how or which subgroups sit within a group.

• Identify normal subgroups, use properties of normal subgroups to determinefactor groups.

• Describe the concept of homomorphism, prover properties of homomorphismsand the subgroups determined by a homomorphism, including applications ofthe First Isomorphism theorem to classify homomorphism.
