Henryk Średnicki (17 January 1955 – 10 April 2016) was a Polish amateur boxer who represented his native country twice at the Summer Olympics, starting in 1976.
Średnicki was best known for winning the world title at the second World Amateur Boxing Championships in 1978, beating Cuba's Héctor Ramírez in the final.
Homework Statement
Verify that (2.16) follows from (2.14). Here \Lambda is a Lorentz transformation matrix, U is a unitary operator, M is a generator of the Lorentz group.
Homework Equations
2.8: \delta\omega_{\rho\sigma}=-\delta\omega_{\sigma\rho}
M^{\mu\nu}=-M^{\nu\mu}
2.14...
\intdt' G(t-t') f(t') = 1/i \delta/\deltaf(t)
where G(t-t') = i/ 2w exp (iw (t-t'))
I thought the RHS of the first equation is f(t). Can someone explain?
thank you
I have been working through Srednicki this summer to teach myself qft, and all too often I've gotten stuck on a small point and ended up spending a great deal of time clearing it up by myself. While this is probably an important part of the learning process, I am progressing a bit too slowly, so...
Could someone help me how in this book by Srednicki I get from eq. 54.23 to 54.24?
thank you
(The book is free on the net, I'm not allowed yet to post the link on this forum, maybe some other can do.)
Homework Statement
Srednicki problem (8.8)
Under a free-field theory, calculate <A|0> , where |A> is the real sclar field's eigenket
Homework Equations
The Attempt at a Solution
I am trying to write <A|0> into path integral formulation, but it is hard.
