Alejandro Ginory
Department of Mathematics - Hill Center
Rutgers, The State University Of New Jersey
110 Frelinghuysen Rd.
Piscataway, NJ 08854-8019

Blurb:

My interests include representation theory, algebraic combinatorics, and experimental mathematics. More importantly, I am currently thinking about Verlinde algebras, affine Kac-Moody Lie algebras, theta functions, non-homogeneous symmetric functions, convergence of iterates of a nonlinear operators, representations of double affine Hecke algebras, and undergraduate mathematical proof comprehension.

Office:

Room 618, Hill Center, Busch Campus

Hours: 2 - 3 PM Tuesdays

Directions: There are two pairs of elevators in the Hill building. One of them goes up to the fifth floor and the other goes up to the seventh. Choose wisely.

Random Math 351 Exercises:

Prove that for every pair of integers a and b (not both zero), every common divisor of a and b divides the greatest common divisor of a and b.
Let R be a ring with identity element 1 and let S be the set {0,1,2,...,n,n+1,...}. Prove that if R is an integral domain and S is finite, then |S| is prime.
(a) Find examples of commutative rings R (not necessarily with identity) and maximal ideals m such that m is NOT a prime ideal.
(b) Let R be a commutative ring (not necessarily with identity) such that for every x in R, x is in Rx. Prove that all maximal ideals in R are prime ideals.
Let p be a prime number. Prove: If G is a group of order p, then G is cyclic. Also prove: If G is a group of order p^2, then G is abelian.
