The Leslie matrix is a discrete, age-structured model of population growth that is very popular in population ecology named after Patrick H. Leslie. [1] [2] The Leslie matrix (also called the Leslie model) is one of the most well-known ways to describe the growth of populations (and their projected age distribution), in which a population is closed to migration, growing in an unlimited ...
In linear algebra, an invertible matrix is a square matrix that has an inverse.In other words, if some other matrix is multiplied by the invertible matrix, the result can be multiplied by an inverse to undo the operation.
Đạo is a Sino-Vietnamese word for "religion," similar to the Chinese term dao meaning "path," while Mẫu means "mother" and is loaned from Middle Chinese /məuX/. While scholars like Ngô Đức Thịnh propose that it represents a systematic worship of mother goddesses, Đạo Mẫu draws together fairly disparate beliefs and practices.
