i am have trouble understanding the difference between these two things and why is nonalbenian used in qft.
Haelfix said:When we talk about abelian groups, it means :
let a, b be elements of a group G. A group is abelian <--> ab = ba.
Groups are constructed and utilized in field theory primarily b/c we notice the laws of nature satisfy certain symmetries called gauge transformations. For instance the U(1) gauge group of electromagnetism is an abelian group and its the simplest example of relevance in the standard model.
Harder to deal with are nonabelian groups where the above property is not satisfied, and there are several examples (like QCD, where the gauge group is SU(3) -color).

Albenian is a term used to describe people, cultures, or languages that are native to Albania. Nonalbenian refers to anything that is not from Albania. The main difference between the two is their origin or connection to Albania.
While there may be some similarities between Albenian and nonalbenian languages, they are generally considered to be distinct from each other. Albenian is an Indo-European language, while nonalbenian languages can vary greatly in their origins and structures.
The population of Albenians is significantly smaller compared to nonalbenians. As of 2021, the estimated population of Albania is around 2.8 million, while the global population is over 7.8 billion. Therefore, nonalbenians make up the majority of the world's population.
Albenian and nonalbenian cultures can have a variety of religions, as there is no one specific religion associated with either. However, the majority of Albenians are Muslim, while nonalbenians can follow various religions such as Christianity, Hinduism, Buddhism, etc.
Some notable Albenian figures include Mother Teresa, a Catholic nun and missionary, and Ismail Kadare, a renowned novelist and poet. Nonalbenian figures can vary greatly depending on their country or culture of origin, but some notable ones include Mahatma Gandhi, Albert Einstein, and Nelson Mandela.
