Hello Coreform! In the U-spline paper on your website, what is the meaning of a “trace space” found in section 4.3? Where can I read more about this concept?
Hello, kaba! I’m sure that others may have more resources on this, but I found the wikipedia page on the Trace operator to be helpful on the topic: https://en.wikipedia.org/wiki/Trace_operator
The trace is basically the restriction of a function to the boundary of the domain over which it is defined.
Thank you, Caleb. This seems to be the answer.
