Symmetries and exact solutions of a reaction-diffusion system arising in population dynamics

Philip Broadbridge, Roman Cherniha, Vasyl' Davydovych +1

A system of two cubic reaction-diffusion equations for two independent gene frequencies arising in population dynamics is studied. Depending on values of coefficients, all possible…

An age-structured diffusive model for epidemic modelling: Lie symmetries and exact solutions

Roman Cherniha, Vasyl' Davydovych

A new age-structured diffusive model for the mathematical modelling of epidemics is suggested. The model can be considered as a generalization of two models suggested earlier for t…

Multi-Meta-RAG: Improving RAG for Multi-Hop Queries using Database Filtering with LLM-Extracted Metadata

Mykhailo Poliakov, Nadiya Shvai

The retrieval-augmented generation (RAG) enables retrieval of relevant information from an external knowledge source and allows large language models (LLMs) to answer queries over…
