GMA Visions Seminar

Keith Schneider, "Minimal Non-Gatherable Triples in Non-Affine and Affine Weyl Groups, and General Haircare Tips," Phillips 367, 4:00pm

                                                          ABSTRACT

After a brief discussion of the properties of Weyl groups we will define the term Minimal Non-Gatherable Triple (Min-NGT). Then we will present a classification of all Min-NGT's in non-affine Weyl groups and a partial classification of Min-Ngt's in Weyl groups.

Ergodic Theory and Dynamical Systems Seminar

Professor Evgeniya Bakunova, "Examination of Some Minutiae of the Collatz Conjecture," Phillips 383, 3:30pm, Refreshments in Phillips 330 at 3:00pm

                                                          ABSTRACT

I have been working on the Collatz conjecture (the 3x+1 problem) and want to present my work in progress, as well as discuss where my ideas stand in relation to the others' working on the same problem.

Analysis/PDE Seminar

Professor Joseph Cima, UNC-CH, "Introduction to H1," Phillips 381, 4:00-5:00 pm

                                                          ABSTRACT

A proof of a homogeneous "div-curl" lemma and again how can one get functions in the Hardy 1 space. (Paper of Meyer, Semmes, Coiffman, et.al.) See a chapter in M.Taylor's book on tools used in PDE.

If time allows I will give a proof of a result of Jones ,
Zinsmeister, Iwaniec, Bonami and an interesting bounded operator mapping BMO into a space called the "Hardy-Orliz" space.

Physically Inspired Mathematics Seminar

Professor Boris Kupershmidt, University of Tennessee,"A Proof of The Riemann's Conjecture." Phillips 385, 3:00 pm

                                                          ABSTRACT

The Riemann's Conjecture had been proved in 1984 by Guy Robin to be equivalent to the inequlity: sigma(n)/n<exp(gamma) *loglog(n) vor n large enough. Here sigma(n) is the sum of positive integer divisors of an integer n. "Gamma" is the Euler costant=0.577... I prove the Robin's inequality by first strengthening it.
