劉虎 (鉄弗部)




劉 虎（りゅう こ、拼音：Liú Hŭ、? - 341年没）は、中国五胡十六国時代の匈奴鉄弗部大人（たいじん：部族長）。別名烏路孤。『晋書』では劉武と表記。南匈奴の右賢王去卑の孫。


曾孫の赫連勃勃から景皇帝と追尊されている。



生涯


誥升爰の子として生まれる。


309年、父が死ぬとそのあとを継ぎ、「鉄弗（父が匈奴人、母が鮮卑人の意）」と号す。


初めは拓跋部に臣従していたが、310年、白部の挙兵に呼応して鉄弗部も挙兵し、并州刺史劉琨のいる新興・雁門の2郡を攻めた。劉琨は拓跋部に援軍を要請し、拓跋部大人拓跋猗盧が甥の拓跋鬱律率いる2万騎を派遣して、白部を撃ち破り、次に劉虎を攻め、その陣営を落とした。劉虎は西走して朔方に逃れ、漢の劉聡のもとに帰順した。劉聡は劉虎の宗室をもって彼を楼煩公に封じ、安北将軍・監鮮卑諸軍事・丁零中郎将に拝した。


318年、劉虎は朔方に拠り、代国西部に侵攻した。しかし代王の拓跋鬱律に大敗し、劉虎は敗走して塞を出た。この時、劉虎の従弟の劉路孤は部落を率いて代国に帰順し、拓跋鬱律の娘を娶った。


341年10月、劉虎は代国の西の国境に侵攻。代王の拓跋什翼犍は軍を派遣し討伐、これを大破した。この後まもなく劉虎は死去し、子の劉務桓が立った。

Can a sorcerer learn a 5th-level spell early by creating spell slots using the Font of Magic feature?

Image
28 6 $begingroup$ Per the Font of Magic feature, sorcerer can use Flexible Casting to create 5th-level spell slots at level 7, even though they are not typically available until level 9. You can transform unexpended sorcery points into one spell slot as a bonus action on your turn. The Creating Spell Slots table shows the cost of creating a spell slot of [5th level is 7] If such a sorcerer levels up while still having this 5th-level spell slot, can they choose a 5th-level spell as the spell they gain upon levelling up? The Spellcasting feature states: Additionally, when you gain a level in this class, you can choose one of the sorcerer spells you know and replace it with another spell from the sorcerer spell list, which also must be of a level for which you have spell slots.

Does disintegrating a polymorphed enemy still kill it after the 2018 errata?

Image
up vote 13 down vote favorite 1 After the 2018 errata, the disintegrate spell description now reads: A creature targeted by this spell must make a Dexterity saving throw. On a failed save, the target takes 10d6 + 40 force damage. The target is disintegrated if this damage leaves it with 0 hit points. If you were to polymorph an enemy into a rat and then disintegrate it, would the enemy be disintegrated or would it just return to its original form? I know that for Druids, it’s not an instant kill anymore, but is this the case for polymorph as well? dnd-5e spells polymorph errata share | improve this question edited 18 hours ago

A Topological Invariant for $pi_3(U(n))$

Image
3 3 $begingroup$ Recently, I saw a construction of topological invariant for $pi_3(U(n))$ with $ngeq 2$ : $$ N=frac{1}{24pi^2}int_{S^3} d^3x epsilon^{ijk} Tr[(U^{-1}partial_{x_i}U)(U^{-1}partial_{x_j}U)(U^{-1}partial_{x_k}U)] , $$ where $Uin U(n)$ depends on $boldsymbol{x}=(x_1,x_2,x_3)in S^3$ , $epsilon^{ijk}$ is the Levi-Civita symbol, $i,j,k=1,2,3$ , and the duplicated indexes are summed over. It is claimed that $N$ is an integer, but why? Update 02/02/2019 I think I got an argument for $n=2$ . In this case, $U=e^{i varphi} q$ with $qin SU(2)$ . Due to the trace and the Levi-Civita symbol in $N$ , $varphi$ does not contribute to $N$ . As $Tr[q^{dagger}partial_i q]=0$ and $(q^{dagger}partial_i q)^{dagger}=-q^{dagger}partial_i q$ , $q^{dagger}partial_i q$ in geneeral has the form $q^{dagger}partia
