Non-linear physics is the study of systems where the output is not directly proportional to the input. Unlike linear systems, which follow simple, predictable relationships, non-linear systems exhibit ...

This example shows the use of the %PDL macro for polynomial distributed lag models. Simulated data is generated so that Y is a linear function of six lags of X, with the lag coefficients following a ...

We study the bilinear Hilbert transforms and bilinear maximal functions associated to non-flat polynomial curves and obtain uniform Lr estimates for r > $r \textgreater \frac {d-1} {d}$, where d is ...

The award was made in recognition of their paper A polynomial-time approximation algorithm for the permanent of a matrix with non-negative entries, which they had presented at the STOC meeting two ...
