TI - Universality of certain diagonal quadratic forms for matrices over a ring of integers PY - 2024/// CY - New Delhi PB - Springer KW - Humanities and Applied Sciences N2 - In 2018, Jungin Lee [5] gave a necessary and sufficient condition for a diagonal quadratic form where for all i, for representing all matrices over . In this paper, we will consider the imaginary quadratic field . Its ring of integers is a principal ideal domain. is the only imaginary quadratic field such that is a principal ideal domain and 2 is a product of two distinct primes in (upto units). With as above, in this paper we give a necessary and sufficient condition for a diagonal quadratic form where to represent all matrices over UR - https://link.springer.com/article/10.1007/s13226-022-00345-3 ER -
