Negative definiteness is a concept from linear algebra and functional analysis, particularly in the context of matrices and quadratic forms. A matrix \( A \) is said to be negative definite if it satisfies the following conditions: 1. **Square Matrix**: The matrix \( A \) is a square matrix (i.e., it has the same number of rows and columns). 2. **Negative Eigenvalues**: All eigenvalues of the matrix \( A \) are negative.
Positive definiteness is a mathematical property that pertains to certain types of matrices, functions, and quadratic forms. It is particularly relevant in the fields of linear algebra, optimization, and statistics.
Quasiperiodic tiling refers to a type of tiling of a plane that exhibits order without periodicity. This means that while the pattern does not repeat itself at regular intervals (as it would in periodic tiling), it still has a structured arrangement that follows certain mathematical rules. One of the most famous examples of quasiperiodic tiling is the Penrose tiling, discovered by mathematician Roger Penrose in the 1970s.
Edward Hutchinson Synge was an influential figure in the field of mathematics, particularly known for his contributions to topology and algebra. However, there seems to be limited widely accessible information about him, and he is not as well-known as some of his contemporaries.
