As an application of some results established, a concrete example about the computation of the spherical spectrum of a compact quaternionic operator with form of infinite direct sums of quaternionic matrices is also given.}, journal = {International Journal of Mathematical and Computational Sciences}, volume = {10}, number = {1}, year = {2016}, pages = {15 - 18}, ee = {https://publications.waset.org/pdf/10003650}, url = {https://publications.waset.org/vol/109}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 109, 2016}, }
