A gauge transformation of a vector bundle or principal bundle is an automorphism of this object. For a principal bundle, a gauge transformation consists of a diffeomorphism φ : P → P {\displaystyle \varphi :P\to P} commuting with the projection operator π {\displaystyle \pi } and the right action ρ {\displaystyle \rho } .
Geometric transformations can be distinguished into two types: active or alibi transformations which change the physical position of a set of points relative to a fixed frame of reference or coordinate system (alibi meaning "being somewhere else at the same time"); and passive or alias transformations which leave points fixed but change the ...
In geometry, inversive geometry is the study of inversion, a transformation of the Euclidean plane that maps circles or lines to other circles or lines and that preserves the angles between crossing curves. Many difficult problems in geometry become much more tractable when an inversion is applied.
The school library was set up in 1982 with the assistance of the Sri Lanka Library Services Board. In 1996, a program titled "Library Week" was inaugurated during the "Reading Month". Library facilities are provided to all the pupils of the school and there are two libraries separately; one for Primary Grades and other for seniors.
