Byreformulating the original equation into a system of equivalentloaded integro-differential equations, we establish sufficientconditions ensuring the existence and uniqueness of the solution.The study focuses on determining the multidimensional kernelassociated with the fractional heat conduction operator. Theapproach is based on the contraction mapping principle and the useof Riemann-Liouville fractional integrals, providing a mathematicalframework applicable to diffusion processes with spatialheterogeneity and memory effects.</p></abstract><kwd-group xml:lang="en"><kwd>heat conduction</kwd><kwd>inverse problem</kwd><kwd>fractional calculus</kwd><kwd>kernel identification</kwd><kwd>fixed-point method.</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">$$textbf{References}$$</mixed-citation><mixed-citation xml:lang="en">$$\textbf{References}$$</mixed-citation></citation-alternatives></ref><ref id="cit2"><label>2</label><citation-alternatives><mixed-citation xml:lang="ru">begin{enumerate}</mixed-citation><mixed-citation xml:lang="en">\begin{enumerate}</mixed-citation></citation-alternatives></ref><ref id="cit3"><label>3</label><citation-alternatives><mixed-citation xml:lang="ru">bibitem{1}</mixed-citation><mixed-citation xml:lang="en">\bibitem{1}</mixed-citation></citation-alternatives></ref><ref id="cit4"><label>4</label><citation-alternatives><mixed-citation xml:lang="ru">Hall, M.R. {it Materials for Energy Efficiency and Thermal Comfort in Buildings}.
