Fridays
---------------------------------------------------------------------------------------
Analysis and
Differential Equations On Separable Banach Spaces
(New Seminar Series)
TBA
About the series:
This series will discuss a new constructive approach
to analysis on
separable Banach spaces.
The key idea is to first show that any separable Banach space
can be continuously embedded in a separable Hilbert
space.
Organizers: Tepper Gill, Dan
Williams, Tim
Myers.
---------------------------------------------------------------------------------------------
Mathematics

Fridays 4.10 to 5 pm, Room 213, ASB-B
No seminar
scheduled for August 30.
Friday, September
6, 12.10 to 1pm
Notice the special
timings for that Friday.
Neil Hindman, Howard Math Dept

Fluid
dynamics seminar
Seminar takes place after colloquium
and does not take place if there is no colloquium.
�Fluid Dynamics Seminar� is also known as the
departmental happy hour.

Please register and as usual, encourage others to
register.
Please feel free to broadcast the workshop on your
network etc.

ANNOUNCEMENTS
---------------------------------------------------------------------------------------------
1.
Roberto de Leo has published two papers.
a. Quasiperiodic Dynamics
and Magnetoresistance in Normal Metals
https://link.springer.com/article/10.1007/s10440-018-00235-z
This paper, joint work with A. Ya. Maltsev (Landau Inst., Russia),
is a review of some important but not very well known
results
on the theory of planar sections of triply periodic
surfaces.
The novelty is that here results are stated, for the
first time in literature,
from the point of view of quasiperiodic
functions,
in order to move the focus of these results from
topology to analysis.
The paper also contains some new preliminary numerical
result
on the genus-4 case.
This is the first paper
published within my NSF grant DMS-1832126.
2. Conjectures about simple
dynamics for some real Newton maps on R^2.
https://www.worldscientific.com/doi/abs/10.1142/S0218348X19500993
In this paper I study numerically the dynamics of the
root-finding Newton method in R^2.
This is a generalization of the case, studied
thoroughly in literature,
of the dynamics of the Newton method in one complex
variable.
I am particularly fond of this
paper because it is my first work that is
100% "HU-based": it came from a random
discovery I made while preparing
examples for the first graduate class I taught at HU
(Numerical Analysis) and
all computations were performed on the CoAS computational cluster that
I was able to purchase a few years ago thanks to
internal research funds
by the Provost (http://helios.physics.howard.edu/).
2. Muhammad Mahmood got funding this Summer from DoD of
which he is the
PI of amount $689,952.00 for three years to work on,
"Fast Chemical Transformations in Energetic
Materials under
conditions of High Pressure, Temperature and Strain Rates",
with two postdoc
fellows.

SCHOLARSHIP
AND FELLOWSHIP OPPORTUNITIES
(from various sources)
—————————————————————————————
NSF
Graduate Research Fellowship Program (GRFP)
(Thanks to Muhammad Mahmood).
Interested students should begin at the
applicant information page
The GRFP supports outstanding graduate
students in NSF-supported science,
technology, engineering, and mathematics
disciplines who are pursuing
research-based master's and doctoral degrees at
accredited United States
institutions.
The program provides up to three years
of graduate education support,
including an annual
$34,000 stipend.
Applications for Mathematical Sciences
topics are due October 25, 2019.
US citizens and permanent residents who
are planning to enter graduate school in
fall 2020 are eligible
(as are those
in the first two years of such a graduate program,
or who are returning to graduate school
after being out for two or more years).
The program solicitation
(http://www.nsf.gov/funding/pgm_summ.jsp?pims_id=6201 ) contains full details.
The GRFP awards more than 1,500 new
fellowships each year.
In the years 2013 through 2019, GRFP
awards in the mathematical sciences
have been given to more than 550 students
who earned baccalaureate degrees
from 190 colleges and universities
throughout 45 states.
The number of baccalaureate
institutions has been growing through the years.
The GRFP also needs qualified faculty
reviewers.
Review panels are conducted by
videoconference.
Please see the panelist information
page
(http://www.nsfgrfp.org/panelist_info)
and consider volunteering to serve as a
panelist by
registering at https://nsfgrfp.org/panelists .

INTERESTING
ARTICLES AND WEBSITES
----------------------------------------------------------------------------------------------
1. Sensational
Proof of Sensitivity Conjecture (Theoretical Computer Science)
Article from Quanta magazine:
Decades-Old
Computer Science Conjecture Solved in Two Pages
Apparently a key tool in this proof by Hao Huang of Emory University is Cauchy�s
interlacing theorem
for eigenvalues of matrices.
