Hold this as a prompt, not a verdict. Two constructs sitting close in meaning is a reason to read them side by side and decide for yourself whether they are one idea under two names. It is not proof that they are. Compare the meanings in the Collider.

In analysis, the support of a function is the smallest closed region outside which the function is zero, that is, the closure of the set of points where it takes a nonzero value. The term entered mathematics through Laurent Schwartz's 1950 Théorie des distributions, which named the support of a distribution as the smallest closed set beyond which it has no effect, carrying the idea from ordinary functions over to generalized ones. Here the referent is a region of a domain, a purely geometric and topological object, and it has nothing to do with help exchanged between people, a material that carries a catalyst, or a count of how often items appear together.[1]
In data mining, the support of an itemset is the fraction of records in a dataset that contain all of its items, a measure of how common that combination is. Agrawal, Imielinski, and Swami's 1993 Mining association rules between sets of items in large databases introduced support, together with confidence, as the thresholds an association rule must clear to be counted as interesting. The referent is a frequency computed over a table of transactions, not help between people, a region of a function, or a material that carries a catalyst.[4]

Social and health psychology
the help, comfort and information a person receives through relationships, and the belief that such help is available.Social support is the help, comfort, and information a person receives through their relationships, and the belief that such help is there if needed. Sidney Cobb's 1976 Social Support as a Moderator of Life Stress framed it as information leading a person to believe they are cared for, valued, and part of a network of mutual obligation, and Cohen and Wills's 1985 Stress, social support, and the buffering hypothesis refined how it protects health, whether directly or by cushioning the impact of stress. The referent is a property of a person's social relationships and its effect on wellbeing, not a region of a function, a carrier for a catalyst, or a frequency in a dataset.[2][3]
