A resilient function $f: X^n to \{0,1\}$, for some set $X$, is such that every subset of coordinates of bounded size has small influence on the function. Such functions have applications in computer science, and are of independent interest of study...

In 1975 Goppa suggested a general method for constructing error correcting codes based on algebraic geometry. In a long line of research such codes were constructed, constituting as a precious example of a construction that beats the probabilistic...

Joint work with Ivan Smith. Let p be a positive integer. Take the quotient of a 2-disc by the equivalence relation which identifies two boundary points if the boundary arc connecting them subtends an angle which is an integer multiple of ($2 \pi / p...
