Graduate student at Boston University.

Some of my favorite questions (that I hopefully answered correctly):

  1. Generalized central binomial coefficients convolution

  2. Is $g(\eta)$, as defined in the question, a Dirac delta function?

  3. How do we know $\sin$ and $\cos$ are the only solutions to $y'' = -y$?

  4. Evaluate $\int_0^\infty \log\left(x^2+t^2\right)e^{-x^2/(2t)}\,dx$?

  5. Covariance of polynomials of random normal variables

  6. Fourier Transform of $\log{|x|} \text{sign}(x)$

  7. Thermal center of a set

  8. I want to show that the polynomial below has integer coefficients.

  9. Average value of $\frac{x'A^2x}{x'A^3x}$ over surface of $n$-dimensional sphere

  10. How to approximate a sharply peaked function with deltas?

  11. Taking seats on a plane - with biased probability

  12. Inverting an equation involving a sum of shifted functions
