the Pi function, i.e. the Gamma function when offset to coincide with the factorial; the complete elliptic integral of the third kind; the fundamental groupoid; osmotic pressure; represents: Archimedes' constant (more commonly just called Pi), the ratio of a circle's circumference to its diameter; the prime-counting function
λProlog, also written lambda Prolog, is a logic programming language featuring polymorphic typing, modular programming, and higher-order programming.These extensions to Prolog are derived from the higher-order hereditary Harrop formulas used to justify the foundations of λProlog.
In the field of representation theory in mathematics, a projective representation of a group G on a vector space V over a field F is a group homomorphism from G to the projective linear group = /, where GL(V) is the general linear group of invertible linear transformations of V over F, and F ∗ is the normal subgroup consisting of nonzero scalar multiples of the identity transformation (see ...
In physics, a sigma model is a field theory that describes the field as a point particle confined to move on a fixed manifold. This manifold can be taken to be any Riemannian manifold , although it is most commonly taken to be either a Lie group or a symmetric space .
In physics, and especially scattering theory, the momentum-transfer cross section (sometimes known as the momentum-transport cross section [1]) is an effective scattering cross section useful for describing the average momentum transferred from a particle when it collides with a target.
1921: Pi Student Chapter was formed in Toronto thereby expanding Alpha Omega into an international scope; 1924: First non-US alumni chapter was founded in Toronto; 1932: (October 7), merger with Alpha Zeta Gamma completed with chartering of Alpha Kappa and Alpha Lambda. 1936: Alpha Omega establishes the Achievement Medal.
Thus, Alpha Sigma Phi gained five chapters from the merger. Unlike Alpha Sigma Phi's mergers with Phi Pi Phi and Alpha Kappa Pi, there was no blanket invitation to Alpha Gamma Upsilon alumni to be initiated into Alpha Sigma Phi. However, some of the more prominent leaders of Alpha Gamma Upsilon did so.
