We present 75 new examples of complex quadratic fields that have 5-rank of their class groups $\geqslant3$. Only one of these fields has 5-rank of its class group >3 ...

Abstract: Decision variables in numerous practical systems can frequently be characterized using a Hermitian quadratic form in complex Gaussian variates. Performance analysis involving these variates ...

Abstract: It has been known for a long time that quadratic modular number codes admit an unusual representation of complex numbers which leads to complete decoupling ...
