Abstract

•We study the analysis suitable T-spline spaces as a piecewise polynomials space.•We characterize the difference between two neighboring polynomial expressions.•We study when the space can be described by smoothness conditions.

In this article we provide the characterization of analysis suitable T-spline spaces (Beirão da Veiga et al., 2013) as the space of piecewise polynomials with appropriate linear constrains on the subdomain interfaces. We describe AST-meshes for which the linear constrains are equivalent to smoothness conditions and provide examples showing that this is not always the case.
