Subject: John L. Greenstadt Obituary

Obituary
John Lester Greenstadt
October 8, 1924 - October 17, 2022

John L. Greenstadt, researcher in applied mathematics, died on October
17, 2022 just after his 98th birthday. He was born October 8, 1924 in
Manhattan, NY to Alice (Fischler) and Morris ("Moe") Greenstadt.
Recognizing John's talent in mathematics, the U.S. army employed him
to work on flight engineering and artillery targeting during the
height of World War II. After leaving the military at the rank of
sergeant, John earned a BA in Physics at Brooklyn College and then
attended Yale University on the GI Bill, where in 1953 he received a
PhD in mathematical physics. He worked as a physicist at H.K. Ferguson
Co. while finishing his degree before joining IBM as a staff scientist
from 1952-1985, during which time he published several important
papers that continue to have impact today. He was one of the first to
use a variational technique to derive a better numerical optimization
method-work in the 1970s that, as he reminisced in a 2000 article ("An
Abridged History of Cell Discretization" LNCSE 11), stimulated the
development of the ubiquitous BFGS method that appears in so many
computational toolboxes today. One current researcher reports, "In my
software I use a 'Greenstadt modification' to keep something called
working weight matrices positive-definite." Another finds "the & work
of Dr.  Greenstadt both deep and inspiring. So, I would say that
Dr. Greenstadt was a great thinker to be memorialized forever."

John will also be remembered by the Mountain View community for his
incisive wit, playful humor, and prodigious knowledge of a variety of
subjects from politics to history to art to music. Not one to suffer
fools gladly, he nonetheless charmed friends and acquaintances with
his gentle consideration and sweetness. He maintained his physical and
mental acuity until the very end of his life when, sadly, the death of
his beloved wife of over 20 years, Karen Lynn Greenstadt, spurred a
decline in his own health. Even in the hospital, though, he continued
to joke with the medical staff and, they said, brought a bright spot
to their days.

John will be mourned by his brother Bill and niece Amy ("Eliza")
Greenstadt, as well as his sister-in-law Nancy Bush and his wife
Karen's son, Paulie Germano. He is also survived by two adult children
from a previous marriage and a granddaughter.

Subject: Improved possible proof of Goldbach's Conjecture

Last summer I published a notice here about a possible proof of
Goldbach's Conjecture, which asserts that each even positive integer
>= 4 is the sum of two primes.

There have been more than 300 visits to the paper, with only three
claims of an error.  Each of these turned out to be the result of a
misunderstanding of the basic argument.  I have now clarified the
argument and in the process reduced the length of the possible proof
to one page.

See "Current Possible Proof" on p. 1 of "A Possible Proof of
Goldbach's Conjecture" on occampress.com.  I will welcome knowing the
first sentence that the reader believes contains an error, and what
that error is.

Subject: Postdoc Position, Orebro Univ, Sweden

Orebro University and the School of Science and Technology are looking
for a postdoc in mathematics.

The project is about data completion problem for motion capture
systems.  Motion-capture systems are used for investigating and
improving various mechanical processes. There are many ways of
tracking motion using such systems. In the project we focus on the
problems associated with the usage of passive markers and video
recording. This type of tracking requires that the markers are visible
in the video which is not always the case. Therefore, tracking the
motions may become problematic or even impossible and, therefore, a
sophisticated method for completing the data from the missing markers
is needed.

The purpose of this issue is to demonstrate soliton solutions, Darboux
transformations, symmetry of differential equations and Hamiltonian
structure, and so on.

Soliton theory and integrable systems are important aspects of
mathematical physics. Subtopics include soliton solutions, symmetry
analysis, Darboux transformation, Hamiltonian structure, and so on.

Darboux transformation of integrable equations is an important tool
for searching for soliton solutions through spectral problems or Lax
pairs.  Symmetry obtained by the Lie group of transformations is
important in the unusual properties of ordinary differential equations
and partial differential equations, which has extensive applications
in physics science.
