theorem Th48: :: MESFUN16:48

for I being non empty closed_interval Subset of REAL
for J being Subset of REAL
for y being Element of REAL
for f being PartFunc of [:RNS_Real,RNS_Real:],RNS_Real
for g being PartFunc of [:REAL,REAL:],REAL
for Pg2 being PartFunc of REAL,REAL
for E being Element of L-Field st y in J & dom f = [:I,J:] & f is_continuous_on [:I,J:] & f = g & Pg2 = ProjPMap2 (|.(R_EAL g).|,y) & E = I holds
Pg2 is E -measurable
