Gus Lee
Augustus Samuel Mein-Sun Lee was born in San Francisco on August 8, 1946, the only son of Tsung-Chi Lee and Da-Tsien Tsu. His three sisters had been born in mainland China and accompanied his mother on the difficult trek across China to India and then to the United States in 1944. There, the family rejoined Tsung-Cbi, wbo had once been a major in the Kuomintang army and who, since 1939, had been working in San Francisco for the Bank of Canton. When Gus was only five, his mother died of breast cancer, and his father, two years later, married a severe Pennsylvania Dutch woman. Gus grew up in the Panhandle and the Haight, a predominantly African American area of San Francisco, and he had a difficult time becoming accepted. He joined the Young Men\u27s Christian Association (YMCA) and learned to box
Robert E. Lee and Slavery
Robert E. Lee was the most successful Confederate military leader during the American Civil War (1861–1865). This also made him, by virtue of the Confederacy\u27s defense of chattel slavery, the most successful defender of the enslavement of African Americans. Yet his own personal record on both slavery and race is mottled with contradictions and ambivalence, all which were in plain view during his long career. Born into two of Virginia\u27s most prominent families, Lee spent his early years surrounded by enslaved African Americans, although that changed once he joined the Army. His wife, Mary Randolph Custis Lee, freed her own personal slaves, but her father, George Washington Parke Custis, still owned many people, and when he died, Robert E. Lee, as executor of his estate, was responsible for manumitting them within five years. He was widely criticized for taking the full five years. Lee and his wife supported the American Colonization Society before the war but resisted the abolitionist movement. Lee later insisted that his decision to support the Confederacy was not founded on a defense of slavery. During both the Maryland (1862) and Gettysburg (1863) campaigns, Lee\u27s officers kidnapped free blacks and sold them into slavery. By 1865, Lee supported the enlistment of African Americans into the Confederate army, but he surrendered before a plan could be implemented. After the war, he generally opposed racial and political equality for African Americans.[excerpt
Should we Banish Robert E. Lee & his Confederate Friends? Let\u27s Talk.
After 152 years, Robert E. Lee is back in the headlines. But not in any way he could have imagined.
The “Unite the Right” forces descended on Charlottesville, Va., to protest calls for the removal of an equestrian statue of Lee that has been sitting in a city park since 1924. The larger question, however, was about whether the famous Confederate general was also a symbol of white supremacy.
The same issues were in play in May when a statue of Lee was removed from Lee Circle in New Orleans. There are also more than two dozen streets and schools named for Lee that have become debating points about symbols of white nationalism. One Army installation in Petersburg, Va., bears Lee’s name; another, Fort Hamilton in New York City, names a driveway for him. (excerpt

Dedication of Robert Lee Moore Hall
Robert Lee Moore Hall, located in the northeast section of the campus, at the southeast corner of the intersection of 26th Street and Speedway, is named for Professor Emeritus Robert Lee Moore, distinguished University of Texas mathematician. The building, which was first occupied in the Fall Semester of 1972-1973, is constructed of warm tan brick and contains classrooms, laboratories, and general offices for the Departments of Astronomy, Mathematics, and Physics.Friday, October 5th, 1973, 5:40pm.

Ghost Busting: PT-Symmetric Interpretation of the Lee Model
The Lee model was introduced in the 1950s as an elementary quantum field
theory in which mass, wave function, and charge renormalization could be
carried out exactly. In early studies of this model it was found that there is
a critical value of g^2, the square of the renormalized coupling constant,
above which g_0^2, the square of the unrenormalized coupling constant, is
negative. Thus, for g^2 larger than this critical value, the Hamiltonian of the
Lee model becomes non-Hermitian. It was also discovered that in this
non-Hermitian regime a new state appears whose norm is negative. This state is
called a ghost state. It has always been assumed that in this ghost regime the
Lee model is an unacceptable quantum theory because unitarity appears to be
violated. However, in this regime while the Hamiltonian is not Hermitian, it
does possess PT symmetry. It has recently been discovered that a non-Hermitian
Hamiltonian having PT symmetry may define a quantum theory that is unitary. The
proof of unitarity requires the construction of a new time-independent operator
called C. In terms of C one can define a new inner product with respect to
which the norms of the states in the Hilbert space are positive. Furthermore,
it has been shown that time evolution in such a theory is unitary. In this
paper the C operator for the Lee model in the ghost regime is constructed
exactly in the V/N-theta sector. It is then shown that the ghost state has a
positive norm and that the Lee model is an acceptable unitary quantum field
theory for all values of g^2.Comment: 20 pages, 9 figure

Review Essay of “Men and the War on Obesity: A Sociological Study”
A review is presented of the book Men & the War on Obesity: A Sociological Study, by Lee F. Monaghan
The Karoubi envelope and Lee's degeneration of Khovanov homology
We give a simple proof of Lee's result from [Adv. Math. 179 (2005) 554-586;
arXiv:math.GT/0210213], that the dimension of the Lee variant of the Khovanov
homology of a c-component link is 2^c, regardless of the number of crossings.
Our method of proof is entirely local and hence we can state a Lee-type theorem
for tangles as well as for knots and links. Our main tool is the "Karoubi
envelope of the cobordism category", a certain enlargement of the cobordism
category which is mild enough so that no information is lost yet strong enough
to allow for some simplifications that are otherwise unavailable.Comment: This is the version published by Algebraic & Geometric Topology on 4

Renormalization in Coulomb gauge QCD
In the Coulomb gauge of QCD, the Hamiltonian contains a non-linear Christ-Lee
term, which may alternatively be derived from a careful treatment of ambiguous
Feynman integrals at 2-loop order. We investigate how and if UV divergences
from higher order graphs can be consistently absorbed by renormalization of the
Christ-Lee term. We find that they cannot.Comment: 23 pages, 26 figure
