Every origin-fixing reflection or dilation is a conformal linear transformation, as is any composition of these basic transformations, including rotations and improper rotations and most generally similarity transformations. However, shear transformations and non-uniform scaling are not. Conformal linear transformations come in two types ...
k = −1 corresponds to a point reflection at point S Homothety of a pyramid. In mathematics, a homothety (or homothecy, or homogeneous dilation) is a transformation of an affine space determined by a point S called its center and a nonzero number k called its ratio, which sends point X to a point X ′ by the rule, [1]
In Euclidean space, such a dilation is a similarity of the space. [2] Dilations change the size but not the shape of an object or figure. Every dilation of a Euclidean space that is not a congruence has a unique fixed point [3] that is called the center of dilation. [4] Some congruences have fixed points and others do not. [5]
In relativistic quantum field theories, the possibility of symmetries is strictly restricted by Coleman–Mandula theorem under physically reasonable assumptions. The largest possible global symmetry group of a non-supersymmetric interacting field theory is a direct product of the conformal group with an internal group. [4]
Point Arena, formerly known as Punta Arena (Spanish for "Sandy Point") [3] is a small coastal city in Mendocino County, California, United States. Point Arena is located 32 miles (51 km) west of Hopland, [5] at an elevation of 118 feet (36 m). [3] The population was 460 at the 2020 census, [4] making it one of the smallest incorporated cities ...
Sea Lion Cove State Marine Conservation Area (SMCA) is a marine protected area that lies onshore, just south of Point Arena in Mendocino County on California’s north central coast. The marine protected area covers 0.22 square miles (0.57 km 2 ).

The first European to record Point Arena was Spaniard Bartolomé Ferrer in 1543, who named it Cabo de Fortunas ("cape of fortunes"). in 1775, lieutenant Juan Francisco de la Bodega y Quadra (commander of the schooner Sonora) renamed the cape Punta Delgado ("narrow point") during a royal expedition chartered by the Viceroyalty of New Spain to map the north coast of Alta California.
