Full homomorphisms to graph classes

Pavol Hell, César Hernández-Cruz

Given a family of graphs $F$ , we define a graph $G$ to be fully $F$ -colourable if $G$ admits a full homomorphism to some $F$ in $F$ . We approach the p…

Measurement of Born Cross Section for $e^{+} e^{-} \to K_{S}^{0} I^ˉ ^{+} I^£^{-} + c.c.$ at $s = 3.51 - 4.95$ GeV

BESIII Collaboration, M. Ablikim, M. N. Achasov +759

Using $e^{+} e^{-}$ collision data collected with the BESIII detector at the BEPCII collider corresponding to a total integrated luminosity of 44~fb $^{- 1}$ , we present the first measure…
