On constant angle surfaces constructed by polynomial space curves with Frenet-like curve frame

In this study, the constant angle ruled surfaces constructed by polynomial space curves using the Frenet-like curve (Flc) frame in Euclidean 3-space are examined. We find the conditions for the ruled ...

Mathematicians make a breakthrough on 2,000-year-old problem of curves

Mathematicians just made a big leap forward on one of the field’s all-time favorite problems. Curves—squiggly lines through space, such as a comet’s trajectory or a stock market trend—are some of math ...
