SUMMARY
The discussion focuses on determining whether the subset U of all 4x4 upper symmetric matrices is a subspace of the vector space V of all M4x4 matrices. Participants emphasize the importance of demonstrating operational closure under addition and scalar multiplication to validate U as a subspace. The concept of upper symmetric matrices is clarified, with suggestions for the original poster (OP) to explore properties of vector spaces and provide counterexamples if necessary. The conversation highlights the need for a systematic approach to proving or disproving the subspace criteria.
