"极简抽象派艺术家" can be translated into English as "Minimalist Abstract Artist" or "Minimal Abstract Artist".
Both expressions are commonly used to describe artists who work within the minimalist and abstract art movements, emphasizing simplicity, reduction of form, and the use of basic geometric shapes or elements. The choice between "Minimalist" and "Minimal" may depend on personal preference or the specific context in which the term is being used, but both are generally understood and accepted.
