Exponential may refer to any of several mathematical topics related to exponentiation, including:

• Exponential function, also:
  • Matrix exponential, the matrix analogue to the above
• Exponential decay, decrease at a rate proportional to value
• Exponential discounting, a specific form of the discount function, used in the analysis of choice over time
• Exponential growth, where the growth rate of a mathematical function is proportional to the function's current value
• Exponential map (Riemannian geometry), in Riemannian geometry
• Exponential map (Lie theory), in Lie theory
• Exponential notation, also known as scientific notation, or standard form
• Exponential object, in category theory
• Exponential time, in complexity theory
• in probability and statistics:
  • Exponential distribution, a family of continuous probability distributions
  • Exponentially modified Gaussian distribution, describes the sum of independent normal and exponential random variables
  • Exponential family, a parametric set of probability distributions of a certain form
  • Exponential smoothing, a technique that can be applied to time series data
• Exponential type
  • Exponential type or function type, in type theory
  • Exponential type in complex analysis
• Topics listed at list of exponential topics

Exponential may also refer to:

• Exponential Technology, a vendor of PowerPC microprocessors
