recurrentes

Recurrentes is the plural form of the adjective recurrente in Spanish, used to describe events, processes or conditions that occur repeatedly over time or return after a period of absence. The term is applied across disciplines to indicate a pattern of recurrence rather than a one-off occurrence.

In medicine and health, recurrentes refers to conditions that reappear after treatment or over a patient’s lifetime. Examples include recurrent infections, fever that recurs, and neurological events such as recurrent seizures. In oncology, cancer may be described as recurrent when it returns after a period of remission; recurrence can be local, regional, or distant (metastatic).

In mathematics and computer science, recurrence denotes dependencies of terms on previous terms. A recurrence relation defines a sequence by specifying how each term relates to earlier ones. Recurrence relations underpin many algorithms and mathematical models, including dynamic programming. In machine learning, recurrent neural networks (RNNs) are designed to handle sequential data by maintaining a hidden state that captures information from previous inputs; variants such as long short-term memory (LSTM) and gated recurrent units (GRU) address practical training issues.

In other domains, recurrence is also used in ecology and epidemiology to describe cycles of populations or events such as seasonal diseases. The concept emphasizes the repeatable nature and temporal structure of the phenomenon.
