Mathematical logic, set theory, lattices and universal algebra form an interconnected framework that underpins much of modern mathematics. At its heart, mathematical logic provides rigorous formal ...

A universal passive logic element of positive and negative logic, made on just one transistor, is proposed. The logic element has at least two inputs, as well as three outputs: an OR, an XOR, and an ...

The possibility of creating passive and active optoelectronic logic elements simultaneously performing the functions AND, NAND, OR, NOR, XOR, XNOR is considered. Passive logic elements, unlike active ...
