In this talk we will look at $n$-variate polynomials that can be expressed as a small (poly$(n)$) sum of powers of linear polynomials. That is, polynomials that have efficient {\em depth-3-powering} circuits.

Given a boolean function $f : \{0, 1\}^n \rightarrow \{0, 1\}$ define the function $f \circ \mathsf{XOR}$ on $2n$ bits by $f \circ \mathsf{XOR} (x_1, \dots, x_n, y_1, \dots, y_n) = f(x_1 \oplus y_1, \dots, x_n \oplus y_n)$. Such a function is cal

A threshold function on n bits is a function that can be represented as the sign of a linear function of its inputs, i.e. f(x) = sign(w_1 x_1 + ... w_n x_n + c)

A set of polynomials is said to be algebraically independent if there is no non-zero combination of them which is zero. Testing whether a given set of polynomials is algebraically independent efficiently is open in general.

In Shannon's classical rate distortion problem, an encoder compresses data from a source into a message and sends it losslessly to the decoder.

This talk will outline standard issues and results related to small noise limits in noise-perturbed dynamics and two important reasonsfor studying these, and illustrate the same by examples from the work ofthe speaker and his collaborators.

Scheduling problems in queueing systems have been long studied under the assumption that the service rates are known a priori.
