Abstract

Esnek küme teorisi, epistemik belirsizlik, muğlaklık ve parametreye bağlı değişkenlik gibi olgularla karakterize edilen sistemlerin modellenmesine yönelik matematiksel olarak titiz ve cebirsel açıdan güçlü bir kuramsal çerçeve sunmaktadır. Bu tür belirsizlik ve varyasyonlar, karar kuramı, mühendislik, ekonomi ve bilgi bilimleri gibi disiplinlerin temelini oluşturan unsurlar arasında yer almaktadır. Bu kuramsal zemin üzerine inşa edilen mevcut çalışma, parametre kümeleri grup kuramsal yapılarla donatılmış esnek kümeler üzerinde tanımlanan yeni bir ikili işlem olan esnek kesişim–yıldız çarpımını tanıtmakta ve kapsamlı bir biçimde analiz etmektedir. Biçimsel tutarlılığa sahip aksiyomatik bir yapı içinde geliştirilen bu işlem, genelleştirilmiş esnek altkümelik ve esnek eşitlik kavramlarıyla uyumlu olacak şekilde kurgulanmıştır. Yürütülen cebirsel çözümleme, işlemin kapalılık, birleşme özelliği, değişme özelliği ve idempotentlik gibi temel yapısal özelliklerine göre ,ncelenmiştir. Ayrıca birim elemanın, ters elemanın ve yutan elemanın varlığı ya da yokluğu ayrıntılı biçimde incelenmiş; işlemin boş ve evrensel (mutlak) esnek kümelerle ilişkisi açık biçimde tanımlanmıştır. İşlemin anlamını daha iyi ortaya koymak amacıyla, literatürdeki önceki ikili esnek çarpım işlemleriyle karşılaştırmalı bir analiz yapılmış; önerilen yapının ifade gücü ve yapısal tutarlılığı, esnek altkümelik kavramlarının katmanlı hiyerarşisi içerisinde değerlendirilmiştir. Elde edilen bulgular, esnek kesişim–yıldız çarpımının, grup yapılı parametre kümelerinin dayattığı tüm aksiyomatik gereklilikleri sağladığını ve böylece esnek kümeler evreni üzerinde sağlam ve içsel olarak tutarlı bir cebirsel yapı oluşturduğunu göstermektedir. Çalışmanın iki temel katkısı öne çıkmaktadır: Birincisi, önerilen işlem, esnek küme teorisinin cebirsel araç dağarcığını biçimsel olarak tutarlı bir işlem çerçevesi içinde anlamlı şekilde genişletmektedir. İkincisi ise, grup yapısına sahip parametrelerle tanımlanan esnek kümelerin, soyut biçimde tanımlanmış işlemler aracılığıyla klasik grup davranışlarını andıran bir yapı sergilediği genelleştirilmiş bir esnek grup teorisinin temellerini atmaktadır. Kuramsal katkılarının ötesinde, önerilen çerçeve, soyut cebire dayalı esnek hesaplama modelleri için ilkesel bir temel sunmakta olup, bu modeller çok kriterli karar analizi, cebirsel sınıflandırma ve belirsizlik odaklı veri analitiği gibi uygulamalarda yüksek potansiyel taşımaktadır. Sonuç olarak, bu çalışma yalnızca esnek cebir kuramının teorik temellerini güçlendirmekle kalmayıp, aynı zamanda bu kuramın hem matematiksel araştırmalar hem de pratik hesaplama süreçleri açısından taşıdığı önemi vurgulamaktadır.

Soft Intersection-star Product of Groups

Abstract

Soft set theory provides a mathematically rigorous and algebraically expressive framework for modeling systems characterized by epistemic uncertainty, vagueness, and parameter-dependent variability—phenomena central to decision theory, engineering, economics, and information science. Expanding on this foundation, the present study introduces and examines a novel binary operation, the soft intersection–star product, defined over soft sets with parameter domains possessing intrinsic group-theoretic structures. Developed within a formally consistent, axiomatic framework, this operation aligns with generalized concepts of soft subsethood and soft equality. A comprehensive algebraic analysis is on the operation’s core properties—closure, associativity, commutativity, and idempotency. The presence or absence of identity, inverse, and absorbing elements, and the soft product’s behavior concerning the null and absolute soft sets, are precisely delineated. To contextualize the operation, a comparative analysis with prior binary soft products is conducted, elucidating its expressive capacity and structural coherence within the layered hierarchy of soft subset classifications. The findings demonstrate that the soft in-tersection–star product satisfies all axiomatic requirements imposed by group-parameterized domains, thereby inducing a robust and internally consistent algebraic structure on the space of soft sets. Two key contributions emerge: first, the operation substantially extends the algebraic toolkit of soft set theory within a rigorous opera-tional framework; second, it lays the foundation for a generalized soft group theory, wherein soft sets indexed by group-structured parameters mimic classical group behavior through abstractly defined soft operations. Beyond its theoretical value, the proposed framework offers a principled basis for soft computational modeling grounded in abstract algebra. Such models are highly applicable to multi-criteria decision analysis, algebraic classification, and uncertainty-sensitive data analytics. Hence, this study not only strengthens the theoretical foundations of soft algebra but also reinforces its relevance to both mathematical research and practical computation.
