摘要內容：
In a Russian Math Survey 2004 paper, Barndorff-Nielsen and Schmiegel propose a non-Gaussian spatial-temporal random field for dynamic modelling of turbulence. We introduce this BN-S space-time field, and describe some fractal geometry for this field, with a view toward a proper non-Gaussian aspect of B.B. Mandelbrot's paper on turbulence iso-surfaces in J. Fluid Mechanics 1974. Recent progress on nonlinear moment-scalings of the stationary exponential processes is also reported, and is toward the stochastic intermittency field proposed in BN-S. The talk is based on the speaker’s article to appear in FRACTALS.
