Mathematical colloquium in BMSTU

We present two practical and widely applicable methods, including some criteria and
a general procedure, for detecting Brunnian property of a link, if each component is
known to be unknot. The methods are based on observation and handwork. They are
used successfully for all Brunnian links known so far. Typical examples and extensive
experiments illustrate their efficiency. As an application, infinite families of Brunnian
links are created and we establish a general way to construct new ones in bulk. This is a joint work with Weibiao Wang.
