We show that these operators are subspace-hypercyclic and there are subspace-hypercyclic  operators that are not subspace-frequently hypercyclic. There is a criterion like to subspace-hypercyclicity criterion that implies subspace-frequent hypercyclicity and if an operator $T$ satisfies this criterion, then $T\oplus T$ is subspace-frequently hypercyclic. Additionally, operators on finite spaces can not  be subspace-frequently hypercyclic.}, keywords = {Subspace-frequently hypercyclic operators,Subspace-hypercyclic operators,Frequently hypercyclic operators,Hypercyclic operators}, url = {https://scma.maragheh.ac.ir/article_43323.html}, eprint = {https://scma.maragheh.ac.ir/article_43323_429d1de82424303d55ed2572e19b75cd.pdf} }
