Phonetic Transcription

/tɛn.sər sʌm/

Meaning and Usage

The term "tensor sum" refers to a mathematical operation which combines two tensors of the same type and order by performing addition in a manner analogous to vector addition. This operation is significant in fields such as physics, engineering, and computer science, particularly in areas like machine learning and general relativity.

Frequency of Use: "Tensor sum" is a specialized term predominantly used in mathematical and scientific contexts, thus appearing more in written communication, particularly in academic papers and technical literature than in oral speech. Its usage in casual conversation is rare.

Example Sentences: - The tensor sum of two matrices yields another matrix that retains properties from both. - Сумма тензоров двух матриц дает другую матрицу, которая сохраняет свойства обеих.

• Researchers often analyze the properties of the tensor sum in relation to transformation groups.
• Исследователи часто анализируют свойства суммы тензоров в отношении групп преобразований.

Idiomatic Expressions

While "tensor sum" itself does not commonly appear in idiomatic expressions, it is worth noting that the term "tensor" is often utilized in various mathematical contexts. Here are some idioms involving related concepts:

1. The tensor product of two spaces is not always straightforward.

Etymology

The word "tensor" originates from the Latin word "tensio," which means "to stretch." The term was adopted into the mathematical lexicon to describe objects that can be thought of as arrays of numbers that transform in a specific way under change of coordinates, reflecting the idea of stretching in different dimensions. The word "sum" comes from the Latin "summa," meaning "the whole" or "total."

Synonyms and Antonyms

Synonyms: - Tensor addition - Tensor combination

Antonyms: - Tensor product (this is a different type of operation) - Tensor difference (used in the context of subtracting tensors)

In conclusion, the term "tensor sum" plays a crucial role in advanced mathematical discussions and applications, especially within disciplines that involve multidimensional data manipulation.
