The lyf so short, the craft so longe to lerne.
Aleksandar Milivojevic
Graduate student
I am a graduate student at Stony Brook, currently on the job market. I mostly think about (rational) homotopy theory and what it can say about (almost) complex manifolds.
My advisor is Dennis Sullivan.
You can find my CV here.

Some notes
The material below is not intended for publication. All minimal models are in the sense of rational homotopy theory.
- On the sixth k-invariant in the Postnikov tower for BSO(3)
- Some calculations of the rational homotopy type of the classifying space for fibrations up to fiber homotopy equivalence
- A note on the difference between the sum of the Hodge numbers and Betti numbers on a non-Kähler complex manifold
Expository and miscellaneous
A symplectic non-Kähler complex threefold all of whose
odd Betti numbers are even, and some almost-complex four manifolds with no
complex structure. Here is an example of a non-integrable almost complex structure connected by a path to an integrable
complex structure on a smooth manifold of even dimension four or greater.
A discussion on almost complex and stably almost complex structures, and
the obstructions to such structures in low dimensions. You can find the
minimal models of some relevant homogeneous spaces SO(2n)/U(n)
here.
Notes for a talk I gave at the City University of New York Graduate Center K-Theory seminar in November 2018, on setting up and calculating the Frölicher spectral sequence.
Notes for a talk I gave at the Stony Brook Symplectic Geometry student seminar in August 2018, titled "Symplectic non-Kähler manifolds".
Notes for a talk I gave at the Stony Brook graduate student seminar in February 2018 as an introduction to rational homotopy theory.
A 1975 paper by Deligne and Sullivan, Complex vector bundles with discrete structure group,
translated from French to English. Here you can find the original.

Uhlenbeck's "Instantons and Four Manifolds".
I'm occasionally on MathOverflow.
