Definition
Meaning and Definition
A stochastic process that satisfies the Markov property, meaning its future state depends only on its present state, not on its past.
In probability theory and statistics, a Markov process is a mathematical model for random systems that evolve over time without memory. It describes transitions between states in a state space according to certain probabilistic rules. The process is 'memoryless' because predicting the next state requires only knowledge of the current state, not the sequence of events that preceded it. This fundamental property makes Markov processes highly tractable for modeling diverse phenomena, from queueing systems and population genetics to financial markets and speech recognition.
Dialectal Variation
British vs American Usage
Differences
No significant differences in technical definition or usage. Spelling conventions follow standard UK/US patterns for surrounding text (e.g., 'modelling' vs. 'modeling'). Terminology in closely related fields like queueing theory may show minor variations (e.g., 'queue' vs. 'line').
Connotations
Identical technical connotations. The name carries the prestige of the Russian mathematician Andrey Markov. It is a neutral, precise term within mathematics and its applications.
Frequency
Equally high frequency in advanced academic and technical contexts in both varieties. Common in postgraduate mathematics, statistics, computer science, physics, engineering, and quantitative finance literature worldwide.

Common Mistakes When Using “markov process”
- Using 'Markov process' and 'Markov chain' with strict distinction in informal applied settings where they are treated synonymously.
- Assuming all random processes are Markovian.
- Confusing the Markov property (conditional independence) with independence.
- Misspelling as 'Markhov process'.
- Incorrectly applying to systems with evident long-term memory or hysteresis.
FAQ
Frequently Asked Questions
It makes analysis, prediction, and computation vastly simpler. You only need to know the current state to determine probabilities for the future, eliminating the need to track and process the entire history. This leads to tractable mathematics for solving complex problems in optimisation, simulation, and inference.
A Markov chain is a specific type of Markov process. Typically, 'Markov chain' implies a process with a discrete set of states (discrete state space) and often, but not always, discrete time steps. 'Markov process' is the broader term encompassing chains as well as processes with continuous state spaces (e.g., diffusions) and/or continuous time.
Yes. A person's total lifetime earnings are not Markovian because your salary next year depends not just on your current job, but on your entire career history, education, and past promotions. The system has 'memory'. Another example is mechanical wear-and-tear: the future failure probability of a bearing depends on its entire history of load and stress, not just its current condition.
It is named after the Russian mathematician Andrey Andreyevich Markov (1856–1922), who pioneered the study of stochastic processes with this 'memoryless' property in the early 20th century. His initial work analysed the sequencing of letters in Russian literary texts.

Mnemonic
Think of a 'MARKed OVervation' – you only need the current MARK to make an OVerall prediction about the future. The past is irrelevant.
Conceptual Metaphor
A SHORT-SIGHTED WANDERER: The process is like a person walking who only decides where to step next based on where they are standing right now, with no recollection of the path they took to get there.
