Complex numbers are numbers that consist of two parts — a real number and an imaginary number. They are the building blocks of more intricate math, such as algebra.

In geometry, we use them to describe reverse directionality on the number line. In a similar way, imaginary and complex numbers (expressions of the form a + bi, where the real numbers a and b join the ...

Now, on to the subject of complex numbers. We have stayed away from this subject until now simply because we did not want to confuse things. Initially, it is easy to think of signals as “real valued.” ...

We Can't Get Very Far Just Having Zero, So We Turn To One. As zero was the additive identity, one is the multiplicative identity — take any number and multiply it by one, and you get that number ...

The graph below shows the total number of publications each year in Complex Geometry and Algebraic Geometry. References [1] Suita Conjecture and the Ohsawa–Takegoshi Extension Theorem .

A Chinese migrant worker with no college degree has found a solution to a complex math problem – in what appears to be a real life version of the Oscar-winning movie “Good Will Hunting.”. Yu ...

Our February Insights puzzle sent readers on a treasure hunt based on complex numbers. First we provided a bit of a primer, demonstrating that complex numbers (expressions of the form a + bi, where ...
