Abstract: We studied the estimations for coneigenvalues of a matrix, introduced the concept of basic coneigenvalues, and gave some sufficient conditions to identify a nonsingular matrix by means of the constructive geometry method that defines hyperplane in real spaces. Moreover, a new inclusion interval of basic matrix coneigenvalues was also studied and a useful estimation was also given.

Key words: coneigenvalue, basic coneigenvalue, inclusion interval
