A circuit composed solely of components connected in series is known as a series circuit; likewise, one connected completely in parallel is known as a parallel circuit. Many circuits can be analyzed as a combination of series and parallel circuits, along with other configurations .
A principal G-connection on a principal G-bundle over a smooth manifold is a particular type of connection that is compatible with the action of the group . A principal connection can be viewed as a special case of the notion of an Ehresmann connection , and is sometimes called a principal Ehresmann connection .
Cartan's definition of a connection can be understood as a way of lifting vector fields on M to vector fields on the frame bundle F invariant under the action of the structure group K. Since parallel transport has been defined as a way of lifting piecewise C 1 paths from M to F , this automatically induces infinitesimally a way to lift vector ...
An RLC circuit is an electrical circuit consisting of a resistor (R), an inductor (L), and a capacitor (C), connected in series or in parallel. The name of the circuit is derived from the letters that are used to denote the constituent components of this circuit, where the sequence of the components may vary from RLC.
Parallel transport of a vector around a closed loop (from A to N to B and back to A) on the sphere. The angle by which it twists, , is proportional to the area inside the loop. In differential geometry, parallel transport (or parallel translation [a]) is a way of transporting geometrical data along smooth curves in a manifold.
An affine connection is typically given in the form of a covariant derivative, which gives a means for taking directional derivatives of vector fields, measuring the deviation of a vector field from being parallel in a given direction. Connections are of central importance in modern geometry in large part because they allow a comparison between ...
Conversely, they are said to be in parallel if the strain of the ensemble is their common strain, and the stress of the ensemble is the sum of their stresses. Any combination of Hookean (linear-response) springs in series or parallel behaves like a single Hookean spring.
For flat connections, the associated holonomy is a type of monodromy and is an inherently global notion. For curved connections, holonomy has nontrivial local and global features. Any kind of connection on a manifold gives rise, through its parallel transport maps, to some notion of holonomy.
