Deriving the Schwarzschild solution — The Schwarzschild solution is one of the simplest and most useful solutions of the Einstein field equations (see general relativity). It describes spacetime in the vicinity of a non rotating massive spherically symmetric object. It is worthwhile… … Wikipedia
Quadratic reciprocity — The law of quadratic reciprocity is a theorem from modular arithmetic, a branch of number theory, which shows a remarkable relationship between the solvability of certain quadratic equations modulo different prime moduli.Although it allows us to… … Wikipedia
Trivial (mathematics) — In mathematics, the term trivial is frequently used for objects (for examples, groups or topological spaces) that have a very simple structure. For non mathematicians, they are sometimes more difficult to visualize or understand than other, more… … Wikipedia

Fundamental unit (number theory) — In algebraic number theory, a fundamental unit is a generator for the torsion free unit group of the ring of integers of a number field, when that group is infinite cyclic. See also Dirichlet s unit theorem.For rings of the form mathbb{Z} [sqrt… … Wikipedia
Topological degree theory — In mathematics, topological degree theory is a generalization of the winding number of a curve in the complex plane. It can be used to estimate the number of solutions of an equation, and is closely connected to fixed point theory. When one… … Wikipedia
Bruck–Chowla–Ryser theorem — The Bruck–Chowla–Ryser theorem is a result on the combinatorics of block designs. It states that if a ( v , b , r , k , λ) design exists with v = b (a symmetric design), then: : k − λ is a squarewhen v is even, and the diophantine equation: x 2 − … Wikipedia
