Thus, a non-singular matrix is invertible, and a singular matrix is not. We call the linear transformation tA: Rn → Rn non-singular if A is a non-singular matrix, and we call it singular if A is a singular matrix#What is a singular and non-singular operator in quantum mechanics?
(v) Singular and non-singular operator
An operator for which the inverse exists is said to be non-singular. An operator that does not have an inverse is called a singular operator#What is the null operator in quantum mechanics?
Null operator: the zero operator ^0 is such that ^0|ψ⟩=0 0 ^ | ψ⟩ = 0 for all ψ. Its matrix elements are all zero, 0ij=0 0 ij = 0 . Addition of operators: given two operators ^A and ^B with matrix elements Aij A ij and Bij B ij , then the matrix elements of their sum ^A+^B are given by Cij=Aij+Bij#@PhysicsWallah @Skrillex @KidsDianaShow @nhcomedyduniya @nhcomedyduniya @LaoJiangswonderfulmoviecomment @QuantumTech @bhjstorage @ShortsBreak_Official @zeenews @SportsCentralOfficial @GSeriesMusic @khangsresearchcentre1685 @MinutePhysics
