This honor is given by the Columbia College Academic Awards Committee to recognize a faculty’s humanity, devotion to truth, and inspiring leadership.
The Mark Van Doren Award for Teaching has been awarded annually since 1962 and was established in honor of Mark Van Doren GSAS ’21, a Pulitzer Prize-winning poet, novelist, scholar, and legendary teacher who inspired generations of Columbia students.

Prof. Hochster will deliver a talk titled:
“Bounding syzygies and the nature of subrings of polynomial rings”
Abstract: A famous theorem of Hilbert asserts that in the polynomial ring in N variables over a field K, if one repeatedly takes modules of relations (or “syzygies”), the process terminates after at most N steps. One may think of having, at each step, finitely many vectors of polynomials. At the next step one replaces them with finitely many generators for the relations among these vectors. Even if one starts with relations on individual polynomials, one must deal with vectors as one iterates. Recently, there has been a great deal of study of how many steps are needed if one starts with n polynomials of degree d but without any assumption about N. The question was raised by Michael Stillman, and the best answer is not known even for four quadrics or three cubics, nor is it known in general whether there is a bound that depends only on b, n. The talk will survey what is known and discuss recent joint work with Tigran Ananyan that shows such bounds exist in degrees 2, 3, and 4. The methods used raise fundamental questions about the nature of subrings and of ideals in polynomial rings that go far beyond the original motivation. The talk is intended for a general audience.

Prof. Borodin will deliver the following talks:
“Macdonald processes”
Abstract: Our goal is to explain how certain basic representation theoretic ideas and constructions encapsulated in the form of Macdonald processes lead to nontrivial asymptotic results in various ‘integrable’ probabilistic problems. Examples include dimer models, general beta random matrix ensembles, and various members of the (2+1)d anisotropic KPZ and (1+1)d KPZ universality classes, such as growing stepped surfaces, q-TASEP, q-PushASEP, and directed polymers in random media.
April 21, 2014 & April 24, 2014 from 5:30pm-7pm; Room 507 Math
“Gaussian Free Field in beta ensembles and random surfaces”
Abstract: The goal of the talk is to argue that the two-dimensional Gaussian Free Field is a universal and unifying object for global fluctuations of spectra of random matrices and random surfaces. This viewpoint leads to natural Gaussian processes on larger spaces which, despite their explicit covariance structure, so far lack conceptual understanding.
April 25, 2014 from 11am-12pm; School of Social Work, Room 903

“Regularity Structures”
Abstract: When considering the large-scale behaviour of physical models arising naturally in statistical mechanics, one is often lead to stochastic partial differential equations that seem to be nonsensical: they are typically nonlinear with nonlinearities involving products of distributions. Examples of such models are the KPZ equation, the dynamical $\Phi^4_3$ model, the continuous parabolic Anderson model, etc. The theory of regularity structures provides a unified way of interpreting and analysing these equations in a robust way. It also provides a clean separation of the problem into an algebraic, an analytic, and a probabilistic component. I will give an introduction to the main concepts and results of the theory, as well as a number of applications.
