An analysi. i. presented to i.vesti.ate the effects of vari.ble vi.cosi.i.s and thermal strati.i.ati.n on the MHD mi.ed convecti.e heat and mass transfer of a vi.cous, i.compressi.le, and electri.ally conducti.g flui. past a porous wedge i. the presence of a chemi.al reacti.n. The wall of the wedge i. embedded i. a uni.orm nonDarci.n porous medi.m i. order to allow for possi.le flui. wall sucti.n or i.jecti.n. The governi.g boundary layer equati.ns are wri.ten i.to a di.ensi.nless form by si.i.ari.y transformati.ns. The transformed coupled nonli.ear ordi.ary di.ferenti.l equati.ns are solved numeri.ally wi.h fi.i.e di.ference methods. Numeri.al calculati.ns up to the thi.dorder level of truncati.n are carri.d out for di.ferent values of di.ensi.nless parameters. The results are presented graphi.ally, and show that the flow fi.ld and other quanti.i.s of physi.al i.terest are si.ni.i.antly i.fluenced by these parameters. The results are compared wi.h those avai.able i. li.erature, and show excellent agreement.

Si.gle-walled carbon nanotubes （SWCNTs） i. the presence of base flui. flow over a porous wedge play a si.ni.i.ant role compared to those of copper nanoparti.les on absorbi.g the i.ci.ent solar radi.ti.n and transi.i.g i. to the worki.g flui. by convecti.n.

Thi. paper exami.es a steady two-di.ensi.nal flow of i.compressi.le flui. over a verti.al stretchi.g sheet. The flui. vi.cosi.y i. assumed to vary as a li.ear functi.n of temperature. A scali.g group of transformati.ns i. appli.d to the governi.g equa- ti.ns. The system remai.s i.vari.nt due to some relati.ns among the transformati.n parameters. After fi.di.g three absolute i.vari.nts, a thi.d-order ordi.ary di.ferenti.l equati.n correspondi.g to the momentum equati.n and two second-order ordi.ary di.ferenti.l equati.ns correspondi.g to energy and di.fusi.n equati.ns are deri.ed. The equati.ns along wi.h the boundary condi.i.ns are solved numeri.ally. i. i. found that the decrease i. the temperature-dependent flui. vi.cosi.y makes the veloci.y decrease wi.h the i.creasi.g di.tance of the stretchi.g sheet. At a parti.ular poi.t of the sheet, the flui. veloci.y decreases but the temperature i.creases wi.h the decreasi.g vi.cosi.y. The i.pact of the thermophoresi. parti.le deposi.i.n plays an i.portant role i. the concentrati.n boundary layer. The obtai.ed results are presented graphi.ally and di.cussed.

The magnetohydrodynami.s （MHD） convecti.n flow and heat transfer of an i.compressi.le vi.cous nanoflui. past a semi.i.fi.i.e verti.al stretchi.g sheet i. the pres- ence of thermal strati.i.ati.n are exami.ed. The parti.l di.ferenti.l equati.ns governi.g the problem under consi.erati.n are transformed by a speci.l form of the Li. symmetry group transformati.ns, i.e., a one-parameter group of transformati.ns i.to a system of ordi.ary di.ferenti.l equati.ns whi.h are numeri.ally solved usi.g the Runge-Kutta-Gi.l- based shooti.g method. i. i. concluded that the flow fi.ld, temperature, and nanoparti.le volume fracti.n profi.es are si.ni.i.antly i.fluenced by the thermal strati.i.ati.n and the magneti. fi.ld.

Arcti. sea-i.e extent reaches i.s mi.i.um each year i. September. On 11 September 2023 the mi.i.um was 4.969 mi.li.n square ki.ometers(***^(2)). Thi. was not a record low, whi.h occurred i. 2012, when the mi.i.um was 4.175 ***^(2), 0.794 ***^(2) less than the mi.i.um i. 2023. However, the i.e extent had decreased by 0.432 ***^(2) compared wi.h 2022. Nevertheless, the summer melti.g i. 2023 was remarkably less than expected when consi.eri.g the strong heat waves i. the atmosphere and ocean, wi.h record temperatures set around the world. i. general, there i. a hi.h correlati.n between the long-term decrease i. sea-i.e extent and the i.creasi.g CO_(2) i. the atmosphere, where the i.crease of CO_(2) i. recent decades explai.s about 80% of the decrease i. sea i.e i.

Si.pler formulas are deri.ed for one-range addi.i.n theorems for the i.teger and noni.teger n generali.ed ex- ponenti.l type orbi.als, momentum space orbi.als, and hyperspheri.al harmoni.s wi.h hyperboli. cosi.e （GETO HC, GMSO HC, and GHSH HC） i. posi.i.n, momentum and four-di.ensi.nal spaces, respecti.ely. The fi.al results are expressed i. terms of one-range addi.i.n theorems of complete orthonormal sets of Ca-exponenti.l type orbi.als, Ca- momentum space orbi.als and za-hyperspheri.al harmoni.s. We noti.e that the one-range addi.i.n theorems for i.teger and noni.teger n-Slater type orbi.als and Gaussi.n type orbi.als i. posi.i.n, momentum and four di.ensi.nal spaces are speci.l cases of GETO HC, GMSO HC, and GHSH HC. The theorems presented can be useful i. the accurate study of the electroni. structure of atomi. and molecular systems.
