Sobolev spaces | Operator theory
In mathematics, the trace operator extends the notion of the restriction of a function to the boundary of its domain to "generalized" functions in a Sobolev space. This is particularly important for the study of partial differential equations with prescribed boundary conditions (boundary value problems), where weak solutions may not be regular enough to satisfy the boundary conditions in the classical sense of functions.

Removing the Spikes Railroad Maintenance (Part 2/14)
When the inspection team has marked the ties to be replaced the next operation is to remove the spikes from the old worn out ties. There are two machines for each track and each machine has one operator to handle the job. The operators job is to align the machine with the spikes to be remo

Watching the Watchers -- How Surveillance Companies Track You Using Mobile Networks
Every day, surveillance companies attack mobile networks, attempting to track the location of mobile phone users. We will analyze, using real-life data, these surveillance companies’ tactics and show the different ways that users are tracked in the wild over 2G, 3G and 4G networks. For 5G,

Trace of an Operator and of a Matrix
Trace of an operator defined to be the sum of the eigenvalues (or of the eigenvalues of the complexification), repeated according to multiplicity. Trace of a matrix defined to be the sum of the squares of the diagonal enties. The connection between these two notions of trace.
