Special Issue Information

Dear Colleagues,

The interaction between geometry and partial differential equations has become one of the most vibrant areas of modern mathematical research. Many central problems in differential geometry, geometric analysis, and mathematical physics are naturally formulated as nonlinear PDEs, while geometric insight often inspires new analytical methods and breakthroughs. This Special Issue, Geometry Meets PDE: Analysis and Applications, aims to showcase recent developments at this rich interface.

Topics include but are not limited to geometric flows (such as Ricci and Yamabe flows), problems in conformal geometry (e.g., the Yamabe problem, the Q-curvature problem, and the prescribed Gaussian curvature problem) AND elliptic partial differential equations (linear, quasi-linear, fully nonlinear equations). Applications of PDE techniques to problems in Riemannian, complex, and conformal geometry are of great interest. Furthermore, we encourage submissions that present new analytical tools motivated by geometric problems, as well as applications of geometric PDEs in broader contexts such as general relativity and geometric topology.

By bringing together diverse perspectives, this Special Issue seeks to highlight common themes and stimulate further progress at the crossroads of geometry and analysis.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Mathematics is an international peer-reviewed open access semimonthly journal published by MDPI.

This study is dedicated to a separable F(R,T)-gravity related to the anisotropic matter to extract the equation of state for F(R,T)-gravity. In this research, we offer insight into calculating the density and pressure in the phantom barrier, stiff fluid, and matter-dominated eras, respectively. As demonstrated, a spacetime in F(R,T)-gravity full of anisotropic matter is a generalized quasi-Einstein spacetime. In addition, we gain the equation of state of Codazzi type, Ricci semi-symmetric and Ricci-pseudo symmetric anisotropic fluid spacetime in F(R,T)-gravity. We prove an anisotropic spacetime in F(R,T)-gravity endowed with Codazzi-type Ricci tensor is a Yang Pure spacetime and Robertson–Walker spacetime. Furthermore, we try to give out the energy constraints of Penrose’s singularity theorem for black holes in an anisotropic fluid spacetime in F(R,T)-gravity. Lastly, we study hyperbolic Ricci solitons on anisotropic fluid spacetime in F(R,T)-gravity endowed with a torse-forming vector field, and for steady hyperbolic Ricci soliton, we deduced the equation of state of anisotropic fluid spacetime in F(R,T)-gravity.
