| Popis: | We present a framework for analyzing nonlinear $$\mathbb {R}^d$$ -valued subdivision schemes which are geometric in the sense that they commute with similarities in $$\mathbb {R}^d$$ . It allows us to establish $$C^{1,\alpha }$$ -regularity for arbitrary schemes of this type, and $$C^{2,\alpha }$$ -regularity for an important subset thereof, which includes all real-valued schemes. Safe bounds on the domain of convergence of the scheme and on the Holder exponent of the limit curves can be found by determining the range of certain real-valued functions. This task can be executed automatically and rigorously by a computer when using interval arithmetics. |
