Abstract In this expository paper, we present some fundamental connections between iterated function systems, in particular those whose attractors are the graphs of multivariate real-valued fractal functions, and foldable figures, affine Weyl groups, and wavelet sets.

Abstract In (Bivens in Mathematics Magazine 65: 226–235, 1992), it is shown that the appearance of the curves completely determines whether a family of curves in the Euclidean plane is a family of level curves of some harmonic function free of critical points. In this paper, we extend the result of (Bivens in Mathematics Magazine 65: 226–235, 1992) to higher dimensional Riemannian manifolds and give a geometric characterization of the level set family of the solutions of the differential equation $$vert {text {grad}};u vert ^{-1}varDelta u=psi$$ |gradu|-1Δu=ψ , where $$psi$$ ψ is a smooth function on the manifold.
在(Bivens In Mathematics Magazine 65: 226-235, 1992)中，证明了曲线的外观完全决定了欧几里得平面上的一组曲线是否为无临界点的调和函数的一组水平曲线。本文将(Bivens在数学杂志65:226-235,1992)的结果推广到高维黎曼流形，并给出微分方程$$vert {text {grad}};u vert ^{-1}varDelta u=psi$$ | grad u | - 1 Δ u = ψ解的水平集族的几何表征，其中$$psi$$ ψ是流形上的光滑函数。
