Open set in R
There is an axiomatic way to define a topology and its topological space. Then any element in the topology is said to be an open set . But another way to define is using the …
Zero to zero power
The fifth postulate of Euclid , in its usual version, tells us that a parallel and only one pass through a point outside a line . However, many geometers did not accept the independence of this postulate and some, including …
Interval (mathematics)
Intervals are called sets of real numbers whose elements x are between two numbers a and b , which satisfy the condition a ≤ b . These are real numbers or represent positive or negative growth trend: symbolized by + ∞ or …
Trident fork
In mathematics a pitchfork bifurcation (in English “pitchfork”) is a type of branch premises of a differential equation of a dynamic system . Trident bifurcations can be supercritical or subcritical . [one] In continuous dynamic systems described by an ordinary differential equation , trident bifurcations occur in systems with …
Transcritical bifurcation
Transcritical bifurcation In mathematics , a transcritical bifurcation is a local or global bifurcation of an ordinary differential equation . This type of branching only occurs when the system has a point that exists for all parameter values that can never be …
Chair-node bifurcation
In mathematics , a saddle-node fork (or tangent, or in English “saddle-node”, “tangent, or” fold “) is a local or global fork of an ordinary differential equation in which two fixed points (or equilibria, or critics) of a dynamic system collide and annihilate …
