We construct a dg-enhancement of KLRW algebras that categorifies the tensor product universal $\mathfrak{sl}_2$ Verma module and several integrable irreducible modules. When modules are two-dimensional, we categorical action blob algebra on derived categories these dg-algebras which intertwines $\mathfrak{sl}_2$. From above derive categorification algebra.

the choice of which products to stock among numerous competing products and how much space to allocate to those products are central decisions for retailers. this study aimed to apply data mining approach so that, we got needed information from large datasets of sale transactions to find the relations between products and to make product assortments. thus, we represented a model for product ass...

A brand name can be considered a mental category. Similarity-based categorization theory has been used to explain how consumers judge a new product as a member of a known brand, a process called brand extension evaluation. This study was an event-related potential study conducted in two experiments. The study found a two-stage categorization process reflected by the P2 and N400 components in br...

How do online customers judge a product’s attributes in cyberspace? Previous studies of online product category suggest that all goods are not equal on the Web, because products have different attributes. Furthermore, the literature assumes that the customer’s ability to evaluate product quality on the Web differs according to product attributes. Based on these considerations, the purpose of th...

Nutrition is a complex behavioral phenomenon that is associated with the specific cultural and environmental issues of each society as well as psychological features.This qualitative research was conducted to identify factors affecting breakfast consumpt...

We consider product markets in which consumers are interested only in a specific product category and initially do not know which product category matches their tastes. Using sophisticated tracking technologies, an intermediary can make inferences about a consumer’s preferred product category and offer advertising firms the possibility to target their ads to match the consumer’s taste. Such tar...
