The term "unconditionally summable" refers to a mathematical property of a series or a sequence where the series or sequence converges regardless of the arrangement of its terms. It indicates that the sum of a series converges to a finite limit without any conditions placed on its summation order.
In mathematical contexts, particularly in functional analysis and related fields, this term is more frequently used in written contexts, especially in scholarly articles, textbooks, and advanced mathematical discussions. Its use in spoken language is relatively less common since it is a specialized term.
Серия, определяемая гармоническими числами, не является безусловно суммируемой.
In functional analysis, we often deal with unconditionally summable sequences.
В функциональном анализе мы часто имеем дело с безусловно суммируемыми последовательностями.
The properties of unconditionally summable series are crucial for understanding convergence behaviors.
While "unconditionally summable" itself is not commonly integrated into idiomatic expressions, its components can be found in various mathematical remarks or discussions. Here are a few expressions related to "summable" that are used in mathematical contexts:
The series is known to be summable. - Известно, что серия является суммируемой.
Absolutely summable: A stronger form where the series of absolute values converges.
An absolutely summable sequence guarantees stability. - Абсолютно суммируемая последовательность гарантирует стабильность.
Geometrically summable: Refers to a series whose terms can be summed using geometric series techniques.
The term "unconditionally summable" derives from the prefix "un-" indicating negation, the root "condition," and "summable" which comes from “sum” (from Latin "summare") meaning to add up. The use of "summable" indicates the ability to total a series of numbers or elements.
