| چکیده | ||
| The article discusses the application of tension field and harmonic maps in image processing. It introduces the concept of (α,f)- harmonic maps, which encompasses both α- harmonic maps and f-harmonic maps, and delves into their characteristics. Furthermore, it presents a Liouville type theorem for this kind of harmonic maps | ||
